1. Let the two numbers be x and y.

   According to the question,

   x + y = 50 ___ eq.(i)

   x – y = 10 ___ eq.(ii)

   By adding both the equation, we get

   2x = 60

   or, x = 60/2 = 30

   By putting the value of x in eq.(i), we get

   30 + y = 50

   or, y = 50 – 30 = 20

   Answer:

   The two numbers are 30 and 20 respectively.
