Question

Sunita has 19 in fifty paise and twenty-five paise coins. She has twice as many twenty
five paise coins as she has fifty paise coins. How many coins of each kind does she
have?​

Answer 1

Answer:

let number of fifty paisa coins = x

number of twenty paisa coins = 2x

1 rupees = 100 paisa

9 rupees = 900 paisa

value of 'x' fifty paisa coins = 50x

value of '2x' twenty paisa coins = 40x

50x + 40x = 900

90x = 900

x = 900/90

.•. x = 10

Hence, no. of fifty paisa coins = 10

no. of twenty paisa coins = 20
