Correct Answer - Option 3 : 30
Given:
Number of 25 paise coins and 50 paise coins is equal
Calculation:
Let x be the number of each type
The purse has an equal number of coins
⇒ 25 paise = 1/4 rupee
⇒ 50 paise = 1/2 rupee
According to the question
⇒ (x/4 + x/2) = 22.50
⇒ (x + 2x)/4 = 22.50
⇒ 3x/4 = 22.50
⇒ 3x = 90
⇒ x = (90/3)
⇒ x = 30
∴ The number of coins of each type is 30
