Let the two numbers be a and b
Then according to question
a + b = 50 ………[1]
a - b = 16
Add two equations
a + b + a - b = 50 + 16
2a = 66
a = 33
If a = 32.5 then from equation [1]
b = 50 - a = 50 - 33 = 17
Two numbers are 33 and 17
Then according to question
a + b = 50 ………[1]
a - b = 16
Add two equations
a + b + a - b = 50 + 16
2a = 66
a = 33
If a = 32.5 then from equation [1]
b = 50 - a = 50 - 33 = 17
Two numbers are 33 and 17

x+y=50
x-y=16
adding
2x=66
x=33
y=17
therefore numbers r 17 and 33
x-y=16
adding
2x=66
x=33
y=17
therefore numbers r 17 and 33
