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.)

View answer & explanation

Correct answer

Answer: (c)C.

(212, 206, 194)

Why this answer is correct

The logic followed here is:

Logic: Second Number = First Number − 6; Third Number = Second Number − 12

For the first set (53, 47, 35)

⇒ 53 − 6 = 47

⇒ 47 − 12 = 35.

For the second set (117, 111, 99)

⇒ 117 − 6 = 111

⇒ 111 − 12 = 99.

Applying the same logic to the set in Option 3

(212, 206, 194)

⇒ 212 − 6 = 206

⇒ 206 − 12 = 194.

Hence, the correct answer is 'Option 3'.
