Correct Answer: 104


Solution : Given:
15 12 81
17 14 93
15 11 ?

Solve according to rows, in each row the sum of the first and the second numbers is multiplied by the result of the subtraction of the second number from the first number to obtain the third number.
First row: (15 + 12) × (15 – 12)  = 27 × 3 = 81
Second row: (17 + 14) × (17 – 14) = 31 × 3 = 93
Similarly, Third row: (15 + 11) × (15 – 11) = 26 × 4 = 104

So, the required number is 104. Hence, the first option is correct.
