Question

A bag contains rs 1 coin and rs 2 coins whose total value is ` 105. If a total number
of `rs 2 coins is thrice the number of rs 1 coin. Find the number of coins of each
type.

Answer 1

Answer:

Number of 1 Rs. coins= x

Number of 2 Rs. coins= 3x

Value of total coins= 105 Rs

x+2(3x)= 105

x+6x= 105

7x= 105

x= 105/7

x= 15

Number of 1 Rs. coins= x= 15

Number of 2 Rs. coins= 3x= 15*3= 45
