Question

a bag contains 50 paisa, 1rupee and 5 rupee coins in the ratio 4:5:3.if the total amount in the bag is 132,then find the total no. of coins in the bag​

Answer 1

Answer:

let the ratio 4:5:3 be 4x, 5x and 3x.

now no. of 0.5 Rs = 4x

So value of 0.5 Rs = (4x)* (0.5) = 2x

no.of 1 Rs = 5x

so value of 1 Rs = 5x

no. of 5 Rs = 3x.

so value of 5rs = 15x

==> 2x + 5x + 15x = 132

so x = 6

Now total no. of coins = 4x+ 5x +3x = 12x = 12*6= 72.
