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

∠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
