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".

h-23=63
Step-by-step explanation:
We must translate this sentence into an equation.
Helena's age decreased by 23 is 63.
The words decreased by tell us to subtract.
In particular, Helena's age decreased by 23 means −h23.
The word is means equals.
So we get the following.
h-23=63
The value of the digit 5 in this number is 50 because 5 is in the tenth place.
