Question
If 55*11 = 33 and 76*16 = 46, then what will be the
value of 49*27 = ?Solution
The logic followed here is that for the numbers X*Y = Z, we have = Z = (X + Y)/2 55*11 = 33 →  (55 + 11)/2 = 66/ 2 = 33 76*16 = 46 →  (76 + 16)/2 = 92/2 = 46 Similarly, 49*27 = ? →  (49 + 27)/2 = 76/2 = 38 Hence, the correct answer is (D).
