Question

the sum of two numbers is 25,and there difference is 5.find the numbers.

Answer 1

Hi dear Shanti....

Let the two numbers be X and Y

according to the question, sum of two no.s is 25

so, X+Y=25⇒X=25-Y...........(1)

and their difference is 5

i.e. X-Y=5⇒X=5+Y.............(2)

Now from equation (1)&(2) we have

25-Y=5+Y

⇒25-5=Y+Y

⇒20=2Y

⇒2Y=20

⇒Y=20/2=10

now u can use the value of Y in equation (1) or (2) to get the value of X.

so let's put in equation (1)

so X=25-Y=25-10⇒X=15

Therefore the required two numbers are 15 & 20 respectively.

Hope u find my ans helpful dear.

All the best Shanti.
