Out of 275 coins, 120 are quarters. Of the remaining coins, 20% are nickels and the rest are dimes and pennies. There are 3 pennies for every dime. How many pennies are there?
A. 31
B. 62
C. 93
D. 124
Total number of coins in question = 275 Number of quarters among the total coins = 120 Then Remaining number of coins = 275 - 120 = 155 Percentage of coins that are nickel = 20% Then Number of coins that are nickel = (20/100) * 155 = 155/5 = 31 Remaining number of coins = 155 - 31 = 124 Ratio of dimes to pennies = 1:3 Let us assume the common ratio to be = x Then x + 3x = 124 4x = 124 x = 124/4 = 31 So The number of pennies = 3 * 31 = 93 From the above deduction we can conclude that there are 93 pennies. The correct option among all the options given in the question is option "C".
