If 14#13 = 9 and 27#36 = 18, then find the value of 46#31.
Show answer & explanation
Correct answer: A
Explanation
Correct Answer: Option 1 — 14
Solution:
The operation # means adding the sum of the digits of both numbers.
-
14 # 13 = (1 + 4) + (1 + 3) = 5 + 4 = 9
-
27 # 36 = (2 + 7) + (3 + 6) = 9 + 9 = 18
Therefore,
-
46 # 31 = (4 + 6) + (3 + 1)
-
= 10 + 4
-
= 14
Hence, Option 1 — 14 is the correct answer.
