Q:

Two concentric circles form a ring. The inner and outer circumference of the ring are 352/7 m and 528/7m respectively.Find the width of the ring.

A) 5 B) 4
C) 3 D) 2
 
Answer & Explanation Answer: B) 4

Explanation:

let the inner and outer radii be r and R meters
then, 2πr = 352/7

 

=> r = (352/7) * (7/22) * (1/2) = 8m
2πR = 528/7

 

=> R= (528/7) * (7/22) * (1/2)= 12m
width of the ring = R-r = 12-8 = 4m

Q:

A runs 123 times as fast as B. If A gives B a start of 80 m, how far must the winning post be so that A and B might reach it at the same time?

A) 200 m B) 300m
C) 270m D) 160m
 
Answer & Explanation Answer: A) 200 m

Explanation:

Ratio of the speeds of A and B =5 : 1 = 5 :3

 

Thus, in race of 5 m, A gains 2 m over B.

 

2 m are gained by A in a race of 5 m.

 

80 m will be gained by A in race of 52*80 m =200m

 

=> Winning post is 200 m away from the starting point.
