RRB Group D Mock Test - 15 - Question 1

### 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 1

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

### Tanya's grandfather was 8 times older to her 16 years ago. He would be 3 times of her age 8 years from now. Eight years ago, what was the ratio of Tanya's age to that of her grandfather?

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

Let, Tanya age 16 years ago = x
Grandfather's age 16 years ago = 8x
8 years from now, 3(x + 16 + 8) = (8x + 16 + 8)
⇒ x = 48/5
8 years ago ratio was:
⇒ z + 8/8z + 8
⇒ 88/424 = 11/53

Let the speed of current be x
and the speed of boat = 6 kmph

∠BOC = 7xo + 20o ; ∠COA = 3xo and AB is a straight line. Find (∠BOC - ∠COA) . Detailed Solution for RRB Group D Mock Test - 15 - Question 43

∠BOC = 7xo + 20o
∠COA = 3xo
we know that
∠BOC + ∠COA = 180o (Linear pair)
7xo + 20o + 3xo = 180o
⇒ 10xo + 20o = 180o
⇒ 10xo = 180o - 20o = 160o
⇒ xo = 160o /10o = 16o
∠BOC = (7 x 16) + 20 = 112 + 20 = 132o
∠COA = 3 x 16 = 48o
∠BOC - ∠COA = 132o - 48o = 84o

In the following questions two equations numbered I and II are given. You have to solve both the equations and give answer.

I. x2 + 5x + 6 = 0
II. y2 + 3y + 2 = 0

Detailed Solution for RRB Group D Mock Test - 15 - Question 90

I. x2 + 5x + 6 = 0
⇒ x2 + 3x + 2x + 6 = 0
⇒ x(x + 3) + 2(x + 3) = 0
⇒ x = -2, -3
Also,

II. y2 + 3y + 2 = 0
⇒ y2 + 2y + y + 2 = 0
⇒ y(y + 2) + 1(y + 2) = 0
⇒ y = -1, -2
Hence, x ≤ y
