Question

A money box contains one-rupee and two-rupee coins in the ratio 5:6. If the total coins in the money box is 85, find the number of two-rupee coins

Answer 1

let the ratio be x

then one rupee coins = 5x

2 rupee coin = 2×6x

= 12x

total value = 85

12x + 5x = 85

17x = 85

x = 85/17

x = 5

one rupee coin = 5×5

= 25

2 rupee coin = 12 × 5

= 60
