Answer 1

Answer:

Suppose the first number is x and second number is y

According to question:

x+y=80  (1)

⇒ x−y=20  (2)

Adding equation (1) and (2)

x+y=80

x−y=20  

=2x=100

x=50

Putting value of x in equation (1)

50+y=80

⇒ y=80−50

⇒ y=30

The required numbers are 50 and 30

2.  let the another number be x

so x(30) =60

x=60÷30

x=2
