Answer 1

Solution

Given :-

• Sum of two number = 125
• Difference between two numbers = 25

Find :-

• Value of these numbers

Explanation

Let,

• First number = x
• Second number be = y

According to question,

Case 1.

==> x + y = 125____________(1)

Case 2.

==> x - y = 25_____________(2)

Add equ(1) & (2)

==> 2x = 125 + 25

==> 2x = 150

==> x = 150/2

==> x = 75

keep in equ(2)

==> 75 - y = 25

==> y = 75 - 25

==> y = 50

Hence

• Value of x = 75
• Value of y = 50
