Answer 2

Heya

Here's the answer

Let the number of 10 rupee coins with Jagdish be x

Value of x 10rupee coins = 10x

Number of 5 rupee coins with him are x+3

Value of x+3 5rupee coins = 5(x+3) = 5x+15

According to the problem

10x+5x+15 = 195

15x+15 = 195

15x = 195-15

15x = 180

x = 180/15

x = 12

Number of 10rupee coins = x = 12

Number of 5 rupee coins = x+3 = 15
