Question
‘11' is related to '1320' following a certain logic.
Following the same logic, '8' is related to '504'. To which of the following is '13' 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 13can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1and 3 is not allowed)Solution
The second number is the difference between the cube of first number and first number. 11 → 11³ - 11 = 1331 – 11 = 1320 8 → 8³ - 8 = 512 – 8 = 504 13 → 13³ - 13 = 169 – 13 = 156
