Question

A cash box contains a certain number of coins, of which 63 are dimes, 33 are nickels, and the rest are quarters. If the probability of selecting a quarter from this bank is 1 5, how many quarters does the bank contain

Answer 1

There are 24 quarters in the cash box.

Explanation:

Since a cash box contains a certain number of coins, of which 63 are dimes, 33 are nickels, and the rest are quarters, if the probability of selecting a quarter from this bank is 1/5, to determine how many quarters does the bank contain the following calculation must be performed:

1/5 = Quarters

4/5 = Nickels and Dimes

4/5 = 63 + 33 = 96

96/4 x 5 = X

24 x 5 = X

120 = X

120 - 96 = 24

Therefore, there are 24 quarters in the cash box.
