The correct answer is C.
A, B and C represent different digits. Plug in different digits for B and find the value of A. Remember that the sum of four 2-digit numbers is another 2-digit number. Therefore, the value of A cannot be more than 2. Why?
A is 1 or 2. The value of 1 for A is not possible. Because the sum of four same numbers (B) cannot be 1, 11 or 21, and 31.
A is 2. So, B can be 3 or 8.
B cannot be 8. Because 4 times 28 is 112, which is not a 2-digit number.
B is 3. Then, C is 9.
A + B + C = 2 + 3 + 9 = 14The Best Books to Ace Algebra
