Question

A bag contains 25 paise, 10 paise and 5 paise coins in the ratio 1 : 2 : 3. If their total value is 760, the number of 5 paise coins is

(a) 10
(b) 50
(c) 30
(d) 40

Answer 1

Answer:
     Let the Number of 25 paisa coins = x
 therefore , Number of 10 paisa coins = 2x
and Number of 5 paisa coins = 3x
Hence Total Value = 25*x + 10*2x +5*3x
                           =25x+20x+15x = 60x      ------   (1)                   
According to Question ,
      total Value = 760            -------------------- (2)
       from 1 and 2 , we get
           60x = 760
         or x =76/6
Hence , Number of 5 Paisa Coins = 3x = 3*76/6 = 76/2 = 38
Hope this helps you!!
