To determine the two numbers, assume the numbers to be 'x' and 'y'. Now, given that the sum of the numbers is 40. Therefore, x + y = 40 --> (A) Also, given that the difference of the numbers is 10. Therefore, x - y = 10 --> (B) Add the equations (A) and (B): 2x = 50, which gives x = 25. Use any of the equations above to determine 'y'. Using equation A: 25 + y = 40, which gives y = 15. Therefore, the numbers are 25 and 15.
(50 + 15) = 65 (50 x 15) = 750 1/50 + 1/15 = 13/150
24 + 26 = 50
