Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE : Operations should be performed on the whole numbers, without breaking
down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding /Subtracting/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)
(3,9,30)
(10,3,33)

Correct option is C

logic is: 1st number × 2nd number + 3 = 3rd number

For the given sets:

For (3, 9, 30): 3×9+3=27+3=30

For (10, 3, 33): 10×3+3=30+3=33

Now, checking the options:

Option (A) (6, 9, 40): 6×9+3=54+3=57, which is not equal to 40.

Option (B) (8, 8, 74): 8×8+3=64+3=67, which is not equal to 74.

Option (C) (12, 3, 39): 12×3+3=36+3=39, which is correct.

Option (D) (9, 7, 98):9×7+3=63+3=66, which is not equal to 98.

Therefore, the correct answer is (c) (12, 3, 39), as it follows the same logic.
