Re: CBSE Class 10th Maths Questions

Here is the list of few Class 10th Maths Questions of CBSE board which you are looking for .

1. Write the condition to be satisfied by q so that a rational number
has a terminating decimal expansion.

2. The sum and product of the zeroes of a quadratic polynomial are - ½ and -3 respectively. What is the quadratic polynomial?

3. For what values of k the quadratic equation x2 - kx + 4 = 0 has equal roots?

5. Which term of the sequence 114, 109, 104, .... is the first negative term?

6. A cylinder, a cone, and a hemisphere are of equal base and have the same height. What is the ratio in their volumes?

7. In the figure given below, DE is parallel to BC and AD = 1cm, BD = 2cm. What is the ratio of the area of ABC to the area of ADE?

8. In the figure given below, PA and PB are tangents to the circle; drawn from an external point P. CD is the third tangent touching the circle at Q. If PB = 10 cm, and CQ = 2 cm, what is the length of PC?


9. Cards each marked with one of the numbers 4, 5, 6....20 are placed in a box and mixed thoroughly. One card is drawn at random from the box. What is the probability of getting an even prime number?

10. A student draws a cumulative frequency curve, for the marks obtained by 40 students of a class, as shown below. Find the median marks obtained by the students of the class.

Section B

11 Without drawing the graphs, state whether the following pair of linear equations will represent intersecting lines, coincident lines or parallel lines: 6x - 3y + 10 = 0 2x - y + 9 = 0 Justify your answer.

12. Without using trigonometric tables, find the value of

13 Find a point on the y-axis, which is equidistant from the points A (6, 5) and B (- 4, 3).

14 In the figure given below, AC is parallel to BD, Is
? Justify your answer.

15 A bag contains 5 red, 8 green and 7 white balls. One ball is drawn at random from the bag, find the probability of getting (i) a white ball or a green ball. (ii) neither a green ball not a red ball. OR One card is drawn from a well shuffled deck of 52 playing cards. Find the probability of getting (i) a non-face card (ii) a black king or a red queen.

Section C

16 Using Euclid’s division algorithm, find the HCF of 56, 96 and 404. OR Prove that
is an irrational number.

17 If two zeroes of the polynomial x4+ 3x3 – 20x2 – 6x + 36 are
and
, find the remaining zeroes of the polynomial.

18. Draw the graph of the following pair of linear equations x + 3y = 6 2x - 3y = 12 Hence, find the area of the region bounded by the x = 0, y = 0 and 2x - 3y = 12.
