Q) The marks obtained by 80 students of class X in a mock test of Mathematics are given below in the table. Find median and the mode of the data: (Q 33 – 30/1/3 – CBSE 2026 Question Paper) Ans: Let’s first rearrange the given data in terms of grouped data: (i) Median value: Step
Q). The length of hypotenuse (in cm) of a right-angled triangle is 6 cm more than twice the length of its shortest side. If the length of its third side is 6 cm less than thrice the length of its shortest side, find the dimensions of the triangle. (Q 35 B – 30/2/3 – CBSE
Q). In a class test, the sum of Anamika’s marks obtained in Maths and Science is 30. Had she got 2 marks more in Maths and 3 marks less in Science, the product of the marks would have been 210. Find the marks she got in the two subjects. (Q 35 A – 30/2/3 –
Q) Represent the following pair of linear equations graphically and hence comment on the condition of consistency of this pair: x – 5 y = 6; 2 x – 10 y = 12. (Q 33 – 30/2/2 – CBSE 2026 Question Paper) Ans: We are given following two equations:Â 1. x – 5 y = 62.
Q) Two different dice are thrown together. Find the probability that the numbers obtained have:(i) even sum (ii) even product. (Q 30 – 30/2/3 – CBSE 2026 Question Paper) Ans: Step 1: We know that in case of n dice, the total outcomes = (6)n ∵ here we have 2 dice, ∴ total outcomes =
Q) The three vertices of a rhombus PQRS are P (2, 3), Q (6, 5) and R (- 2, 1). Find the coordinates of the fourth vertex S and coordinates of the point where both the diagonals PR and QS intersect. (Q 29 – 30/2/3 – CBSE 2026 Question Paper) Ans: Let’s consider the coordinates
Q) Express cos A and tan A in terms of sin A. (Q 25 B – 30/2/3 – CBSE 2026 Question Paper) Ans: Step 1: We know that according to trigonometric identity: sin 2 θ + cos 2 θ = 1 or for θ = A, we can say, sin 2 A + cos 2 A = 1 ∴
