Correct Answer: 99
Solution :
Given:
27 * 4 = 77 and 31 * 9 = 239
Like, 27 * 4 = 77→27 × 4 = 108; 27 + 4 = 31; 108 – 31 = 77
And, 31 * 9 = 239→31 × 9 = 279; 31 + 9 = 40; 279 – 40 = 239
Similarly, follow the same pattern for 21 * 6 = ?→21 × 6 = 126; 21 + 6 = 27; 126 – 27 = 99
So, 99 is the answer to the given equation. Hence, the third option is correct.
