Question

sum of two nos is 125 and difference is 25 find the nos​

Answer 1

75 and 50

Step-by-step explanation:

Let, the two numbers be x and y.

As the sum is 125,

x + y= 125 ——— i

As the difference is 25,

x - y = 25 ——— ii

Adding i and ii, we get

x + y + x - y = 125 + 25

2 x = 150

So, x = 75 ———iii

Putting eq. iii in eq. i, we get

75 + y = 125

y = 125 - 75

So. y = 50

Therefore, the two numbers are 75 and 50.

Answer 2

SOLUTION

GIVEN

Sum of two nos is 125

Difference is 25

TO DETERMINE

The numbers

EVALUATION

Let the numbers are a and b

By the first condition

a + b = 125 - - - - (1)

By second condition

a - b = 25 - - - - - (2)

Adding Equation 1 and Equation 2 we get

2a = 150

⇒ a = 75

From Equation 1 we get

75 + b = 125

⇒ b = 125 - 75

⇒ b = 50

FINAL ANSWER

Hence the required numbers are 75 and 50
