Select the set in which the numbers are related in the same way as the numbers of the following set.
(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)
(4 - 18 - 5)
(7 - 20 - 3)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 6 - 16 - 2.
Logic Used: (First Number + Third Number) × 2 = Second Number
⇒ 4 - 18 - 5 → (4 + 5) × 2 = 9 × 2 = 18
⇒ 7 - 20 - 3 → (7 + 3) × 2 = 10 × 2 = 20
Similarly, For Option 2
⇒ 6 - 16 - 2 → (6 + 2) × 2 = 8 × 2 = 16
