Question

Find out the correct answer for the unsolved equation based on a certain system.

32 + 64 = 15, 84 + 18 = 21, 93 + 24 = ?

• A. 16
• B. 20
• C. 24
• D. 18

Answer 1

Answer:

D. 18

The logic follows here is; Digit Sum of First Number + Digit Sum of Second Number = Third Number (3 + 2) + (6 + 4) = 5 + 10 = 15, (8 + 4) + (1 + 8) = 12 + 9 = 21, Similarly, (9 + 3) + (2 + 4) = 12 + 6 = 18. So, the missing term is 18.
