Question : Directions: In the following number pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the option in which the numbers are related in the same way as the numbers of the following pairs.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Correct Answer: 15, 92
Solution :
Given:
9, 56
17,104
Here, multiply the first number by 6 and then add 2 to the resultant to get the second number –
⇒ 9, 56→9 × 6 + 2 = 56
⇒ 17,104→17 × 6 + 2 = 104
Let's check each option –
First option:
11, 83; 11 × 6 + 2 = 68 ≠ 83
Second option:
8, 51; 8 × 6 + 2 = 50 ≠ 51
Third option:
12, 69; 12 × 6 + 2 = 74 ≠ 69
Fourth option:
15, 92; 15 × 6 + 2 = 92
So, only the fourth option follows the same pattern. Hence, the fourth option is correct.
