Question
In the following question, select the odd number pair
from the given alternatives. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 25 - Operations on 25 such as adding/ subtracting/ multiplying etc. to 25 can be performed. Breaking down 25 into 2 and 5, and then performing mathematical operations on 2 and 5 is not allowed)Solution
The logic followed here is as follows: In each option, the second number is obtained by multiplying the first number by 3. In option A: 64 x 3 = 192 In option B: 82 x 3 = 246 In option C: 47 x 3 = 141 In option D: 73 x 3 = 219 ≠217 In all the number pairs except '73, 217', the second number is exactly thrice the first number. So, '73, 217' is the odd number pair.
