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 2
(137-142-147)
= 137 + 5 = 14 and 142 +5 = 147
(117-122-129)
= 117 + 5 = 122 and 122 + 7 = 127 (odd)
(103-108-113)
= 103 + 5 = 108 and 108 + 5 = 113
(131-136-141)
= 131 + 5 = 136 and 136 + 5 = 141
