Question

There are some 25 paise coins and some 50 paise coins in a bag. The total number of coins is 140 and the amount in the bag is Rs.50. Find the number of coins of each value in the bag.

Answer 1

here are equal number of coins of all three denomination.

The values of each denomination in dollars is 1, 0.5 (50 paise) and 0.25 (25 paise). So, the value of a set consisting one coin of each type = 1 + 0.5 + 0.25 = Rs.1.75

Given that the total value of all the coins present in the bag is Rs.35.

Therefore, there will be 35/1.75 = 20 coins of each type,
