In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which mumbers should replace X and Y so that the pattern followed by the two numbers on the left side of:: is same as that on the right side of :: ? (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) X : 56 : 11 : Y
