Question:

DIRECTIONS: Certain systems are used to solve some equations. Solve the following equations and find what will come in place of question mark.

If 12 × 35 = 28, 29 × 61 = 80, then 43 × 34 = ?

Options:
A) 56
B) 81
C) 72
D) 49
Solution:
Ans:(d) In this pattern, 12 × 35 = (1 + 3) × (2 + 5) = 4 × 7 = 28 and 29 × 61 = (2 + 6) × (9 + 1) = 8 × 10 = 80. Therefore, 43 × 34 = (4 + 3) × (3 + 4) = 7 × 7 = 49.
