Question

a boy contains 1 rupee and 2 rupee coins whose total value is 70 rupees. if no. of 1 rs. coins is 5 times no. of 2 rs coins, find no. of coins for each type

Answer 1

let no. of 2 rs coins be x.

therefore,1 rupee coins=5x

since the no. of coins is given and not values,

1 rupees coins=1*5x=5x
2 rupees coins=2*x=2x
ATP,

$5x + 2x = 70$
$7x = 70$
$x = 10$
therefore,no. of 2 rupees coins is 10.
no. of 1 rupee coins is 50.

hope this helps!!!
