Question : 16 [SSC CGL Prelim 2007]
A box contains 1-rupee, 50-paise and 25-paise coins in the ratio 8 : 5 : 3. If the total amount of money in the box is 112.50, the number of 50-paise coins is
a) 30
b) 42
c) 50
d) 80
Answer »Answer: (c)
Ratio of number of 1 rupee, 50-paise and 25 paise coins
= 8 : 5 : 3
Ratio of their respective values
= $8 : 5/2 : 3/4 = 32 : 10 : 3$
Sum of the ratios
= 32 + 10 + 3 = 45
Value of 50 paise coins

Number of 50 paise coins
