Answer 2

Answer:

The numbers are 45 and 15 .

Step-by-step explanation:

LET THE NUMBERS BE x and y

Given , x + y = 60............(1)

Also ,    x - y = 30.............(2)

On solving (1) & (2),

        x + y = 60

    - ( x - y  = 30)

        2y= 30

⇒ y= 30/2 = 15

Substituting y=15 in (1)

x + 15 = 60

x= 60 - 15 = 45

∴The numbers are 45 and 15 .
