In a 100 m race, A can give B 10 m and C 28 m. In the same race B can give C:

A) 18 m B) 20 m
C) 27m D) 9 m
 
Answer & Explanation Answer: B) 20 m

Explanation:

A : B = 100 : 90.

 

A : C = 100 : 72.

 

B:C = B/A*A/C = 90/100*100/72 = 90/72

 

When B runs 90 m, C runs 72 m.

 

When B runs 100 m, C runs (72/90*100)m = 80m

 

 B can give C 20 m.

Q:

A man buys a trouser in Rs.1250. By reduction of 20% in the price of trouser, he can purchase a t-shirt also in the same amount that was initially paid for the trouser. Find the price of the t-shirt?

A) Rs. 250 B) Rs. 125
C) Rs. 225 D) Rs. 200
 
Answer & Explanation Answer: A) Rs. 250

Explanation:

Initial amount spent on trouser by the man = Rs. 1250

Now, by the reduction of 20% in 1250, he can buy t-shirt too.

=> t-shirt cost = 20% of 1250 = 20 x 1250/100 = 250

 

Therefore, the price of the t-shirt = Rs. 250.
