Answer 1

total coins = 480

ratio among the coins of 1/2, 1/4 and 1/10 Rs are = 5:3:1

let number of coins of 50 paisa = 5x

number of coins of Rs 25 paisa = 3x

number of coins of 10 paisa = 1x


total coins = 480 coins

= coins of 50 paisa + coins of 25 paisa + coins if 10 paisa = 480 coins

= 5x + 3x + 1x = 480 coins
= 9x = 480 coins
= x = 480/9 coins = 53.333333.... coins

coins of 50 paisa = 5x = 5 × 53.33333..... coins
= 266.666666........... coins

coins of 25 paisa = 3x = 3 × 53.33333...... coins
= 160 coins

coins of 10 paisa = 1x = 53.333333....... coins
