Detailed Solution for RRB Group D Mock Test - 15 - Question 1

Let, Tanya age 16 years ago = x

There is a circular pond and a foot-path runs along its boundary. A man walks around it exactly once, keeping close to the edge. His each step is 55 cm long and he takes exactly 440 steps to around once then. The diameter of the pond is

Detailed Solution for RRB Group D Mock Test - 15 - Question 2

Circumference of the outer edge = 55 x440 = 24200 cm
We know that c = 2πr
∴ 24200 = 2 x 22/7 x r
⇒ r = 24200 x 7/2 x 22 = 3850 cm
radius of the outer edge or pond = 3850 cm = 3850/100 = 38.5 m
diameter = 38.5 x 2 = 77 m
