Select the odd group of numbers. (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)
Answer & explanation
Correct answer: option 4
(57-53-49)
(60-56-52)
(50-46-42)
(47-43-37)
The logic followed here is :
Ist number - 4 = second number and second number - 4 = IIIrd number
as
57 - 4 = 53 and 53 - 4 = 49
60 - 4 = 56 and 56 - 4 = 52
50 - 4 = 46 and 46 - 4 = 42
47 - 4 = 43 and 43 - 6 = 37 ODD)
