Question

A purse has only two rupee coins and five ruppe coins. The sum of the coins is 36 and the total value of the coins is 84 find the no of five rupee coins

Answer 1

Answer:

Let the no. Of 2 rupee coin be x

Then,no. of 5 rupee coin=36-x

Therefore,x +36-x= 36

Value:

2 rupee coin =2(x)=2x

5 rupee coin=5(36-x)=180-5x

Then,2x + 180-5x=84

-3x +180= 84

-3x=84-180

-3x=-96

3x=96

x=96/3=32

Therefore number of 5 rupee coins=36-x=36-(32)=4
