Question

The difference of 2 numbers is 3 and their sum is 25. What are the numbers? 10 and 15 14 and 11 11 and 13 13 and 12

Answer 1

Let the two numbers be x and y

As given, the difference of two numbers is 3, so

`x-y=3` or
`x=3+y` ....(1)

And their sum is 25, so

`x+y=25` .....(2)

Putting x=3+y in equation (2)

`3+y+y=25`

`2y=22`

`y=11`

As, x+y=25

`x+11=25`

`x=14`

So the two numbers are = 14 and 11
