Given : Vijay has 50 paise, 25 paise and 10 paise coins in the ratio 4: 7: 11 amounting 485.

To Find : the number of coins of each type respectively.

(A) 400, 700, 1100

(B) 700, 400, 1100

(C) 400, 1100, 700

(D) 700, 1100, 400

Solution:

50 paise, 25 paise and 10 paise coins  4x , 7x , 11x  respectively

Value of 50 paise coins  =  4x * 50 /100  = 2x

Value of 25 paise coins = 7x * 25/100  =  1.75x

Value of 10 paise coins  = 11x * 10/100  = 1.1x

Total Value = 2x + 1.75x + 1.1x

= 4.85x

4.85x = 485

=> x = 100

coins are  400 , 700 and 1100  

Correct option is A)   400, 700, 1100
