In the following question, select the number which can be placed at the sign of question mark (?) from the given alternatives.
Show answer & explanation
Correct answer: D
Explanation
Row 1:
(7 × 4 × 3) + 1 = 84 + 1 = 85
Row 2:
(8 × 3 × 5) + 1 = 120 + 1 = 121
Following the same logic for the third row:
Row 3:
(5 × 6 × 4) + 1
5 × 6 = 30
30 × 4 = 120
120 + 1 = 121
