Q:

Akash leaves mumbai at 6 am and reaches Bangalore  at  10 am . Prakash leaves Bangalore at 8 am and reaches Mumbai at 11:30 am. At what time do they cross each other?

A) 10 am B) 8:32 am
C) 8:56 am D) 9:20 am
 
Answer & Explanation Answer: C) 8:56 am

Explanation:

Time taken by Akash = 4 h

Time taken by Prakash = 3.5 h

For your convenience take the product of times taken by both as a distance.

Then  the distance = 14km

Since, Akash covers half of the distance  in 2 hours(i.e at 8 am)

Now, the rest half (i.e 7 km) will be coverd by both prakash and akash

Time taken by them = 7/7.5 = 56 min

Thus , they will cross each other at  8 : 56am.

Q:

In a race of 200 m, A can beat B by 31 m and C by 18 m. In a race of 350 m, C will beat B by:

A) 22.75 m B) 25 m
C) 19.5 m D) 18.5 m
 
Answer & Explanation Answer: B) 25 m

Explanation:

A : B = 200 : 169.

 

 

 

A : C = 200 : 182.

 

 

 

C/B = (C/A*A/B) = (182/200*200/169) = 182:169

 

 

 

When C covers 182 m, B covers 169 m.

 

 

 

When C covers 350 m, B covers (169/180*350)m  = 325 m

 

 

 

Therefore, C beats B by (350 - 325) m = 25 m.
