Select the odd group of numbers. (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)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (400 –200 –50).
The logic used here is: 1st number ÷ 2 = 2nd number, 2nd number ÷ 2 = 3rd number
Option 1: (600 – 300 –150): 600 ÷ 2 = 300, 300 ÷ 2 = 150
Option 2: (400 – 200 –50): 400 ÷ 2 = 200, 200 ÷ 2 = 100: This does not follow the logic.
