Answer 1

Answer:

Number of 5 rupee coins-->20

Number of 3 rupee coins-->60

Number of 1 rupee coins-->80

Step-by-step explanation:

Let the number of 5 rupee coins be x

Then, number of 3 rupee coins are 3x(as 3 times of no.of 5 rupee coins)

Number of 1 rupee coins+3x+x=160(as 160 coins in total)

Number of 1 rupee coins=160-4x

1(160-4x)+2(3x)+5(x)=300(as sum of the the value of all coins is 300)

160-4x+6x+5x=300

7x=140

x=20

Number of 5 rupee coins-->20

Number of 3 rupee coins-->3*20=60

Number of 1 rupee coins-->160-4(20)=80
