Question
The first number in the given number pairs is obtained
by performing certain mathematical operation(s) on the second number. The same operation(s) are followed in all the number pairs, except one. Find that odd number pair. (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)Solution
The logic followed here is: 1st number = (2nd number)³ + 10. 222 : 6 = 6³ + 10 = 216 + 10 = 226 ≠ 222 353: 7 = 7³ + 10 = 343 + 10 = 353 522: 8 = 8³ + 10 = 512 + 10 = 522 37: 3 = 3³ + 10 = 27 + 10 = 37
