(b) The marks obtained by 30 students in a class assessment of 5 martks is given below:  [3]

Marks 0 1 2 3 4 5
No. of Students 1 3 6 10 5 5

Calculate the mean, median and mode of the above distribution.
(c) In the figure given below, O is the centre of the circle and SP is a tangent. If ∠SRT = 65°, find the value of x, y and z. [4]
icse-previous-papers-with-solutions-for-class-10-mathematics-2015-10Answer 3

(a) Given : Side = 21 cm,
Let Diagonal of the square = √2 (side)
Mode = 3 marks (as highest frequency is 10)
In ∆ OSP,
50° + 90° +z = 180°
∴ z = 40°
