Question

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:

₹ 1 : ₹ 0.50 = 1:3

Total = 1*1+0.5*3 = 1+1.5 = 2.5

2.5 ---------- 35

1 -------------- 14

₹ 1 coins = 14

₹ 0.5 coins = 14*3 = 42

Answer 2

Answer:

Let the kiddy bank have x number one ruppee coin, therefore it has 3x numbers 50p coin.

Therfore, x*1+3x*.50=35,

x+1.5x=35

2.5x=35

x=14

no. of one rupee 14coins, no. of .50paise =3x=14*3=42coins

Therfore x+3x=14+42*.50=14+21=35
