Question

8.
Aravind has a kiddy bank. It is full of one-rupee and fifty paise coins. It contains 3 times
as many fifty paise coins as one rupee coins. The total amount of the money in the bank is
35. How many coins of each kind are there in the bank?
​

Answer 1

Answer:

let number of one rupee coins = x

therefore , number of 50 paisa coins = 3x

Total amount of money = Rs 35

therefore ,

  0.5(3x) + 1(x) = 35

.15x +1x= 35

or 25÷10x=35

or 25x= 35×10

or 25x =350

or x= 14

Therefore , Number of one Rupee coins = 12

∴Hence Number of 50 paisa coins = 3×14 = 42
