This maths quiz for Class 7 brings together big topics that most Class 7 syllabi cover in one quick practice round: integers, simple equations, percentages and simple interest, exponents, mean, median and mode, the angle properties of triangles, the Pythagoras property and the circumference of a circle. There are 15 questions, arranged from easy to hard.
Every item is a Class 7 maths MCQ question with four options, and each answer comes with the working, so students can see exactly where a mistake happened. Many wrong options are the classic slips, such as giving the total amount instead of the interest, or the area instead of the circumference, which makes the quiz a good check for careless errors.
Use it as a revision test before exams, a ten-minute homework check, or a team game in class. Students can play first, then open the answer key below to study all the maths MCQ questions for Class 7 with answers. Playing it again a few days later is a simple way to see what has stuck.
A neat fact to remember: the Pythagoras property was known in ancient India too. The Baudhayana Sulba Sutra, a text on building fire altars, describes the same relationship between the sides of a right-angled triangle.
Maths Quiz for Class 7 questions with answers
Show answers
What is (-3) x (-4)?
- 12
- Minus 12
- Minus 7
- 7
Answer: 12. The product of two negative integers is positive, so (-3) x (-4) = 12.
What is the sum of the three angles of any triangle?
- 90 degrees
- 180 degrees
- 270 degrees
- 360 degrees
Answer: 180 degrees. The angle sum property says the three interior angles of every triangle add up to 180 degrees. The angles of a quadrilateral add up to 360 degrees.
Solve for x: 2x + 3 = 11
- 7
- 8
- 4
- 5
Answer: 4. Subtract 3 from both sides to get 2x = 8, then divide by 2: x = 4. Check: 2 x 4 + 3 = 11.
What is 25% of 80?
- 25
- 40
- 16
- 20
Answer: 20. 25% means one quarter. One quarter of 80 is 80 / 4 = 20.
What is the mean of 2, 4, 6, 8 and 10?
- 6
- 5
- 30
- 8
Answer: 6. Mean = sum of observations / number of observations = 30 / 5 = 6. 30 is only the total.
Which pair of angles is NOT complementary?
- 30 and 60 degrees
- 40 and 60 degrees
- 45 and 45 degrees
- 25 and 65 degrees
Answer: 40 and 60 degrees. Complementary angles add up to 90 degrees. 40 + 60 = 100, so that pair is not complementary.
What is the value of 2 to the power 5?
- 10
- 25
- 32
- 7
Answer: 32. 2 to the power 5 means 2 x 2 x 2 x 2 x 2 = 32. It is not 2 x 5 = 10.
What is the simple interest on Rs 1,000 at 5% per year for 2 years?
- Rs 50
- Rs 105
- Rs 1,100
- Rs 100
Answer: Rs 100. Simple interest = (P x R x T) / 100 = (1,000 x 5 x 2) / 100 = Rs 100. Rs 1,100 is the total amount (principal plus interest).
What is the value of (-1) to the power 101?
- Minus 1
- 1
- 101
- Minus 101
Answer: Minus 1. A negative number raised to an odd power stays negative. Since 101 is odd, (-1) to the power 101 = -1.
What is the mode of 3, 5, 5, 7, 5, 8, 7?
- 7
- 5
- 8
- 3
Answer: 5. The mode is the value that appears most often. 5 appears three times, more than any other number.
The two shorter sides of a right-angled triangle are 6 cm and 8 cm. How long is the longest side?
- 14 cm
- 12 cm
- 10 cm
- 48 cm
Answer: 10 cm. By the Pythagoras property, longest side squared = 6 x 6 + 8 x 8 = 36 + 64 = 100, so the side is 10 cm.
The two interior opposite angles of a triangle are 50 and 60 degrees. What is the exterior angle?
- 70 degrees
- 10 degrees
- 120 degrees
- 110 degrees
Answer: 110 degrees. An exterior angle of a triangle equals the sum of its two interior opposite angles: 50 + 60 = 110 degrees.
What is 0.5 x 0.4?
- 0.2
- 2.0
- 0.02
- 0.9
Answer: 0.2. 5 x 4 = 20, and the two numbers have two decimal places in total, so the answer is 0.20 = 0.2.
Taking pi as 22/7, what is the circumference of a circle with radius 7 cm?
- 22 cm
- 44 cm
- 154 cm
- 88 cm
Answer: 44 cm. Circumference = 2 x pi x r = 2 x 22/7 x 7 = 44 cm. 154 sq cm would be the area (pi x r x r).
In an isosceles triangle, the angle between the two equal sides is 40 degrees. What is each of the other two angles?
- 40 degrees
- 50 degrees
- 70 degrees
- 140 degrees
Answer: 70 degrees. The two base angles are equal and the three angles add to 180 degrees: (180 - 40) / 2 = 70 degrees each.
