SSC GD Maths Questions: Practice With Solutions
Eight Class 10 level practice questions, each solved step by step, with the trap marked.
SSC GD maths questions come from Part C of the computer-based test (CBT), Elementary Mathematics: 20 questions for 40 marks, at Class 10 level, with no calculator. The topics are everyday arithmetic: percentages, ratio, interest, profit and loss, time and work, time and distance, and mensuration.
Below are eight practice questions written for this page, each with a full solution. They are not from any past paper. Try each one before reading the working.

Practice Questions With Solutions: Set 1
- 1
Practice question 1 (percentage): Monthly savings rise from ₹4,000 to ₹4,600. What is the percentage increase?
Increase = 4,600 minus 4,000 = ₹600. Percentage increase = 600 ÷ 4,000 × 100 = 15%. Answer: 15%. Trap: dividing by the new value (600 ÷ 4,600) gives about 13%, which is wrong. Always divide by the original value.

Practice question 2 (LCM): Three bells ring every 12, 18 and 30 minutes. They ring together at 6:00 am. When will they next ring together?
Find the LCM. 12 = 2 × 2 × 3, 18 = 2 × 3 × 3, 30 = 2 × 3 × 5. LCM = 2 × 2 × 3 × 3 × 5 = 180 minutes = 3 hours. Answer: 9:00 am.

Practice question 3 (speed): A runner covers 1.5 km in 6 minutes. What is the speed in km/h?
6 minutes = 6 ÷ 60 = 0.1 hour. Speed = 1.5 ÷ 0.1 = 15 km/h. Answer: 15 km/h. Trap: dividing 1.5 by 6 gives km per minute (0.25), not km per hour.

Practice question 4 (ratio): ₹7,200 is shared between A and B in the ratio 4 : 5. How much does B get?
Total parts = 4 + 5 = 9. One part = 7,200 ÷ 9 = ₹800. B gets 5 × 800 = ₹4,000 (and A gets ₹3,200; check: 3,200 + 4,000 = 7,200). Answer: ₹4,000.

Practice question 5 (simple interest): Find the simple interest on ₹12,000 at 8% per year for 3 years.
Simple interest = principal × rate × time ÷ 100 = 12,000 × 8 × 3 ÷ 100 = ₹2,880. Answer: ₹2,880.

Practice question 6 (time and work): A can finish a job in 12 days and B in 18 days. How long will they take working together?
In one day A does 1/12 and B does 1/18 of the job. Together = 3/36 + 2/36 = 5/36 per day. Days needed = 36 ÷ 5 = 7.2 days, that is 7 1/5 days. Answer: 7.2 days. Trap: averaging 12 and 18 to get 15 days. Working together must take less time than either alone.

Practice question 7 (discount): A pair of shoes is marked ₹1,500 and sold at 10% discount. What is the selling price?
Discount = 10% of 1,500 = ₹150. Selling price = 1,500 minus 150 = ₹1,350. Answer: ₹1,350.

Practice question 8 (mensuration): A rectangular ground is 40 m long and 25 m wide. How far do you run in 3 full rounds of its boundary?
Perimeter = 2 × (40 + 25) = 2 × 65 = 130 m. Three rounds = 3 × 130 = 390 m. Answer: 390 m. Trap: using the area (40 × 25 = 1,000) when the question asks for distance around.
How Part C Tests You, and the Trap
GD maths questions are short, one or two steps each. What they test is whether you read exactly what is asked: per cent of the old value or the new one, km per hour or per minute, area or boundary. Most wrong answers among the options are built from exactly these slips.
Every wrong answer costs 0.25 marks, so a careless slip costs more than leaving the question blank. Write units next to every number in rough work, and check that your answer makes sense before you mark it.
FAQs
How many maths questions are in SSC GD?expand_more
Part C, Elementary Mathematics, has 20 questions carrying 40 marks, as per the 2026 notice.
What level of maths comes in SSC GD?expand_more
Matriculation (Class 10) level arithmetic, solved without a calculator. Algebra and trigonometry are not in the notice's topic list.
Which maths topics should I practise first for SSC GD?expand_more
Start with percentages, ratio and averages, because interest, profit and loss and discount questions are built on them. Then move to time and work, time and distance and mensuration.
