Question
4 is related to 40 following a certain logic. Following
the same logic, 12 is related to 120. To which of the following is 15 related following the same logic? (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 is followed here- 4 is related to 40, 4 x 10 = 40 12 is related to 120, 12 x 10 = 120 Similarly, 15 is related to 150, 15 x 10 = 150
