Question

A toy bank is full of one rupee and 50paise coins. It contains 3 times as many 50 paise coins as one rupee coins. The total amount of money in the toy bank is rs 35.How many coins of each kind are there in the toy bank?

Answer 1

let the no. of 1 rupee coins be x
then the no. 50 Paise coins will be 3x
value of 1 rupee coin will be 1× x= x
value of 50 Paise coins will be 1/2×3x = 3/2x
A/Q
x+ 3/2x = 35
(2x + 3x)/2 = 35
5x / 2 = 35
5x = 35×2
5x= 70
x = 70/5
x= 14

no. of 1 rupee coin is 14
no. of 50 Paise coins is 42.
