Question

A bag contain 10p and 25p coin in the ratios 5:2 if the total money in the bag is rs 100 find the number of 25p coin in the bag

Answer 1

Answer:

Let the number of 25 paise coin= x

So, the number of 10 paise coin = 2x

And similarly the number of 5 paise coin = 3x

Now,

30 Rupees = 3000 paise.

So,

25p×x + 10p(2x) + 5p(3x) = 3000 p

( 25x+20x+15x ) p =3000 p

60x= 3000

x=50

2x= 100

And 3x = 150..

Since number of 25 paise, 10 paise and 5 paise coin are 50, 100 and 150 respectively.
