Question
Three of the following four pairs of numbers are like
in a certain way and one is different. Pick the odd one out. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 - operation 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
10² - 3 = 100 – 3 = 97 13² - 3 = 169 – 3 = 166 15² - 3 = 225 – 3 = 222
