Question

a money box contains one rupee and 2 rupee coins in ratio 3 is to 5 if the total value of the coins in the money box rupees 78 find the number of 1 Rupee coins​

Answer 1

Answer:

18

Step-by-step explanation:

since the ratio of the no. of 1 rupee coins to that of 2 rupee coins is 3:5

let us assume that the no. of 1 rupee coin is 3x

and the no. of 2 rupee coin is 5x

so total value of coins = 3x(1) + 5x(2) = 13x

its given that total value of coins is 78

13x = 78

x=78/13

x=6

therefore no. of 1 rupee coins = 3x = 3*6

=18
