18 1 rupee coin and 30 2 rupee coins

Solution : let us assume the no. of 1 rupee coins and 2 rupee coins as 3x and 5x respectively since they are in the ratio of 3:5.

Now the total value of one rupee coin in the money box would be 3x ×1 .

the total value of 2 rupee coin in the money box would be 5x × 2=10x

Also the total value of money is given as 78

therefore, 3x+10x =78
13x=78
x=6

so the number of 1 rupee coins are 3×6=18
