A lady has only 25-paisa and 50-paisa coins in her purse. If she has 50 coins in all totalling 19.50, how many coins of each kind she have?

Text Solution

Verified by Experts

The correct Answer is:
22, 28
Let the number of 25-p and 50 - p coins be x and y respectively.
Then, ` x + y = 50 and (x)/(4) + (y)/(2) = (1950)/(100)`.
