Question

In a bag, there are coins of 25 paise, 10 paise, and 5 paise in the ratio of 1 : 2 : 3. If there is ₹30 in all, how many 5 paise coins are there?

Options

• 50

• 100

• 150

• 200

Answer 1

150
Explanation:

Let the numbers of 25 paise, 10 paise, and 5 paise coins be x, 2x and 3x, respectively.
Then, sum of their values

= ₹`((25x)/100+(10xx2x)/100+(5xx3x)/100)`

= ₹`(60x)/100`

∴ `(60x)/100=30`

⇒ `x=(30xx100)/60=50`

Hence, the number of 5 paise coins
= (3 x 50) = 150
