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 their 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)
(40, 175, 15) (30, 133, 11)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (25, 91, 12)
The logic used here is:
(40, 175, 15) = 40 - 15 = 25, 25 × 7 = 175
(30, 133, 11) = 30 - 11 = 19, 19 × 7 = 133
Similarly,
(25, 91, 12) = 25 - 12 = 13, 13 × 7 = 91
