Question

A bag contains 25 paise and 50bpaise coins whose total value is RS 30.If the number of 25 paise coins is four times that of 50 paise coins , find the the number of each tupe of coins?

Answer 1

let x be number of 25 paisa coins and
y be number of 50 paisa coins
By data, 4x=y
We know that 50 paise =2×25 paise
so 4x=2y

So ratio is value of 25 paisa coin and 50 paisa coin is 2:1

30÷3=10

Value of 25 paisa coins is 20 ruppess
value of 50 paisa coins is 10 ruppess

1ruppe=100 paisa

So number of 25 paisa coins is given by 4×20=80
number of 50 paisa coins is 2×10= 20
