Question : Directions: Some equations have been solved based on a certain pattern. Find the correct answer for the unsolved equation on that basis.
9 * 8 = 63, 7 * 8 = 49, 5 * 6 = 25, 11 * 7 = ?
Option 1: 77
Option 2: 70
Option 3: 66
Option 4: 121
Correct Answer: 66
Solution :
Given:
9 * 8 = 63, 7 * 8 = 49, 5 * 6 = 25
Like, 9 * 8 = 63→9 × 8 = 72; 72 – 9 = 63
And, 7 * 8 = 56→7 × 8 = 56; 56 – 7 = 49
Similarly, 11 * 7→11 × 7 = 77; 77 – 11 = 66
So, 66 is the answer. Hence, the third option is correct.
