Q:

On selling 17 balls at Rs.720 there is a loss equal to the cost price of 5 balls. Then what is the cost price of a ball is ?

Answer

From given data,


(C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)


C.P. of 12 balls = S.P. of 17 balls = Rs.720.


Hence, C.P. of 1 ball = Rs.720/12 = Rs. 60.

A) loss of 24% B) gain of 28%
C) loss of 28% D) gain of 20%
 
Answer & Explanation Answer: B) gain of 28%

Explanation:

Money invested by Rajan before 1 year was = Rs. 100000

Money in UK pounds @ 75 is = 100000/75 = 1333.33 Pounds

 

Now, after 1 year invested amount was appreciated by 20%

=> 20% of 1333.33 = 266.66

 

Total investment becomes = 1333.33 + 266.66 = 1600 Pounds

This 1600 Pounds @ Indian currency at 80 = 1600 x 80 = Rs. 1,28,000

 

Hence, Rajan's investment of Rs. 1,00,000 becomes Rs. 1,28,000 in 1 year

 

Therefore, his profit % = [(128000 - 100000)/100000] x 100 = 28%.
