NIOS Class 10 Mathematics 211 Solved TMA answers are what most learners come hunting for the moment the booklet lands and the maths starts to feel heavier than expected. Fair enough. The tutor marked assignment quietly carries twenty per cent of your marks in subject 211, and those marks go into a separate column on your NIOS mark sheet, so a tidy, correct submission nudges your result up before you have written a single line in the exam hall.

NIOS Class 10 Mathematics 211 Solved TMA for the October 2026 Session
Every Mathematics 211 learner hands in one tutor marked assignment for the session, and this year's questions stick to the ten lessons NIOS keeps aside for internal assessment. If the whole assignment business still feels a bit murky, our plain-English guide to the NIOS TMA walks you through how you submit it and what the marks are actually worth.
Our solved set tracks the October 2026 paper for code 211 exactly. We keep to the word limits printed on each question, forty to sixty words for the short ones and a hundred to a hundred and fifty for the longer two, and the project in question six comes with a proper labelled figure rather than a vague sketch. Nothing is padded, and nothing is guessed at.

Every Question in the Mathematics 211 TMA for October 2026
Here is the full question set, copied out from the booklet so you can hold it up against your own paper before you order. Every question gives you a choice, and in the file we answer whichever option tends to pick up marks most safely.
Question 1 · Answer any one in about 40 to 60 words
(A) A learner of class 10 was playing with number blocks and suddenly made numbers like 1441, 121, 14578754 and so on. Her teacher explained that these are called "Palindrome Numbers", which read the same forwards and backwards. Write all palindrome numbers less than 100. Is there a particular number that is a factor of all of them? Will the numbers formed be rational or irrational?
(B) Anil was learning the Laws of Exponents. Using those laws: (i) Find the value of x if 5x × 32x−8 = 28,125. (ii) Simplify (20 + 70) / 50.
Question 2 · Answer any one in about 40 to 60 words
(a) Ratul and his friends set up a tent. Two ropes, AB and CD, cross each other at point O, and a third rope OP is tied at the intersection. From the figure, ∠AOP = 3x + 7, ∠BOP = x + 5, and ∠BOD = 40°. (i) What is the value of x? (ii) What is the measure of ∠BOP?
(b) Three friends, Sushma, Salma and Saloma, walk away from a fixed point in three directions such that each path is equally inclined to the other two. (i) Find the angles the paths make with each other. (ii) Name the type of lines formed by tracing the paths.
Question 3 · Answer any one in about 40 to 60 words
(a) A table shows the number of books read by students in a month across the intervals 0–5, 5–10, 10–15, 15–20 and 20–25, with 7, 12, 15, 10 and 6 students. (i) Find the class mark of the interval 15–20. (ii) Convert the frequency table into a cumulative frequency table.
(b) A company records monthly salaries (in thousands of rupees) for the ranges 10–20, 20–30, 30–40, 40–50 and 50–60, with 4, 7, 10, 15 and 9 employees. (i) Calculate the class width of each class. (ii) Explain whether the data is discrete or continuous, with justification.
Question 4 · Answer any one in 100 to 150 words
(a) The upper half of a door is semi-opaque glass in a wooden frame. The ratio of length to breadth of the upper half is 5:3. Subtracting 0.5 feet from the breadth and 1 foot from the length gives the glass portion. Taking length as 5x and breadth as 3x, (i) express the length and breadth of the glass in terms of x, and (ii) give the polynomial for the area of the glass and find its zeros.
(b) A curious student noticed the three consecutive primes 7, 11 and 13 and called them "The Prime Trio". (i) He added the three numbers. What kind of number results, and do all sets of three consecutive primes behave the same way? If not, give a counter-example. (ii) He took a three-digit number such as 157, wrote it again to its right to form 157157, then divided by 7, 11 and 13 in turn. What was the result? Make two more examples and note your observations.
Question 5 · Answer any one in 100 to 150 words
(a) A table shows the production (in million tonnes) of sugar substitutes by six units, A to F, from April to August. (i) In which month does unit B contribute about 15% of total production? (ii) Which unit shows a continuous increase? (iii) For unit F, in which pair of months was production equal? (iv) In July, how many units contribute more than 25% of total production?
(b) (i) A shopkeeper used a bar graph for daily sales and a histogram for customer ages. State two key differences between a bar graph and a histogram. (ii) Draw a histogram for the data in the intervals 1–10, 11–20, 21–30 and 31–40 with frequencies 15, 10, 5 and 8.
Question 6 · Project, prepare any one
(a) Sketch a rectangular village ABCD. Inside it, mark a triangular plot ΔAPD set aside for girls' education, with ∠APD = 60° and ∠PDA = 30°. Take BC as 10 km and extend DC to a point E such that CE = BC. (i) Draw the figure. (ii) Find ∠PAD. (iii) Find ∠BCE. (iv) Find the length BE. (v) If ΔAPD were equilateral, would ΔAPD be congruent to ΔBCE? Why or why not?
Two Sample Answers from Our Mathematics 211 Solved TMA
One honest look at a solved answer tells you more than any promise we could make. So here are two of them, done exactly the way the full file does, one from geometry and one from the number system. Follow the steps, check the logic, and see whether this is the kind of working you would be happy to hand in.
Sample 1 · Question 2(a) · Lines and Angles
Since AB is a straight line, the three angles standing on it at point O add up to a straight angle:
1. ∠AOP + ∠BOP + ∠BOD = 180°
2. Substitute the given expressions: (3x + 7) + (x + 5) + 40 = 180
3. Collect like terms: 4x + 52 = 180, so 4x = 128 and x = 32.
4. Now find the required angle: ∠BOP = x + 5 = 32 + 5 = 37°Answer: x = 32, and ∠BOP = 37°.
Sample 2 · Question 4(b) · Number System
Part (i). Adding the trio gives 7 + 11 + 13 = 31, and 31 is a prime number. The pattern does not always repeat, though. Take the next trio, 3 + 5 + 7 = 15, which is divisible by 3 and 5, so it is composite. The sum of three consecutive primes is therefore sometimes prime and sometimes not.
Part (ii). Writing 157 twice gives 157157. Dividing successively by 7, 11 and 13 is the same as dividing by their product, and 7 × 11 × 13 = 1001. So 157157 ÷ 1001 = 157, the original number. This happens because any three-digit block written twice equals that block times 1001. Two more cases: 248248 ÷ 1001 = 248 and 736736 ÷ 1001 = 736.
Observation: repeating a three-digit number always yields a multiple of 1001, so the three divisions return the original three-digit number every time.
The rest are solved to the same standard in the complete file: the exponent problem in question one, the cumulative frequency and class-width tables in question three, the glass-area polynomial in question four, the production figures in question five, and the whole project drawing in question six.

How We Prepare Each Mathematics 211 TMA Answer
Every answer starts from the prescribed 211 textbook, not some generic solution floating around online. We go to the exact lesson a question belongs to, use the method NIOS expects, and set the steps down in the order a marker likes to see them. That is precisely why the geometry answer above reaches for the straight-angle property first, then does the algebra.
We treat the word limits as real limits. A forty-to-sixty-word question gets a short, complete reply instead of half a page of padding, because markers cut marks for waffle. Project figures are drawn to scale with every angle and length labelled, and each number is checked twice before it goes anywhere near the file. If you want a feel for how we write more widely, have a look through the NIOS Study Material library first.
You can have the set typed or handwritten, whichever suits you. The handwritten one is scanned cleanly and sized to upload straight to the NIOS student dashboard, which is the only route NIOS accepts now.
Who Should Order This NIOS Class 10 Mathematics 211 Solved TMA
This one is for any Secondary learner taking Mathematics 211 who would rather have the internal marks handled properly and on time than lose sleep over them. If maths is the subject that worries you, that twenty per cent from a clean assignment is often the cushion that carries you past the thirty-three per cent pass line even on an average theory day.
It works just as well for confident students who simply have not got the hours to draw the project figure and format six answers to spec. Rather than throw those marks away, they treat our file as a model, and plenty of them pick up the wider NIOS Class 10 Solved TMA bundle at the same time to sort their other subjects in one go.

Why Students Rely on Unnati for Mathematics 211 TMA Help
We have been helping NIOS learners since 2010, and Mathematics is one of the subjects people ask us about most, mostly because it scares them a little. The answers are prepared by tutors who actually teach and mark this syllabus, so the working matches what NIOS evaluators reward instead of some textbook ideal that quietly loses marks on presentation.
And we do not disappear once the file lands in your chat. If a step is unclear, ask, and you will get a real explanation back rather than a shrug. That bit of after-sale help is why so many learners come back for their next subject and point their classmates towards our NIOS Solved TMA service for the same October session.
Frequently Asked Questions on the Mathematics 211 Solved TMA
Is the Mathematics 211 Solved TMA updated for the October 2026 session?
Yes. The solved set matches the current October 2026 question paper for code 211, question by question. We check every answer against the printed word limits and the prescribed textbook before delivery. If NIOS revises the paper mid-session, we update the file and re-share it, so you are never submitting answers to a question that has quietly changed since you ordered.
How many marks does the Mathematics 211 TMA add to my result?
The tutor marked assignment carries twenty per cent of the marks in Mathematics 211, and those marks appear in a separate column on your mark sheet. In practice, a strong assignment can lift a borderline theory score above the thirty-three per cent pass mark. That is why a correct, well-presented file matters far more than students first assume when they treat the TMA as an afterthought.
Do I get typed or handwritten answers for the Mathematics 211 TMA?
Both options are available, and you choose when you order. The typed version is clean and easy to read, while the handwritten version is scanned and sized for direct upload to the NIOS student dashboard. Since NIOS now accepts only online submission through the dashboard, most learners pick the handwritten scan so the file is ready to upload without any extra formatting on your side.
Will you show me a sample before I buy the Mathematics 211 Solved TMA?
You already have two full samples on this page, question 2(a) and question 4(b), worked out exactly as the paid file does it. Those samples let you judge the depth and clarity for yourself. If you would like to see the format of a longer answer or the project figure before ordering, message us and we will share an extra sample page over WhatsApp.
Can Unnati help with subjects beyond the Mathematics 211 TMA?
Yes. Mathematics is one subject among many we cover for NIOS Secondary learners. Once your Mathematics 211 assignment is sorted, we can prepare solved assignments, notes, and previous-paper solutions for your other four subjects too, so your whole internal assessment is handled in one place. Just tell us the subject codes on WhatsApp and we will quote for the full set.
