Question

A bag contains 25 paise and 50 paise coins whose total value is Rs. 30. If the number of 25 paise coins is four times that of 50 paise coins, find the number of 50 paise coins.

• A. 40
• B. 30
• C. 50
  
• D. 20

Answer 1

The correct option is D 20

Total amount in the bag = Rs. 30 = 3000 paise
Let the number of 50 paise coins be x

Then the number of 25 paise coins = 4x

Now, according to the question
25(4x) + 50x = 3000
100x + 50x = 3000
150x = 3000

x = $\frac{3000}{150}$

x = 20

Answer ⇒ 20
