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)

(47-43-37)

(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)
