DSSSB · Reasoning

In the following number-pairs, the second number is obtained by performing certain mathematical operations on the first number. What numbers should come in place of X and Y so that the pattern followed by the two numbers on the left of :: becomes the same as the pattern followed by the two numbers on the right of ::? (Note: Operations should be performed on whole numbers without breaking the numbers into their component digits. Take 13 for example, operations on 13 Like adding/subtracting/multiplying 13, etc. can be done. It is not allowed to break 13 into 1 and 3 and then perform mathematical operations on 1 and 3.)

  1. X=19, Y=26
  2. X=19, Y=24
  3. X=17, Y=24
  4. X=17, Y=32
