Question

two number are such that the ratio between them is 3:5 if each is increased by 10 the ratio between the new number so formed is 5:7 find the original number​

Answer 1

Answer:

Let the numbers be 3x and 5x respectively.

Their ratio =3x/5x=(3/5)

Acc to question,

(3x+10)/(5x+10)=5/7

=7(3x+10)=5(5x+10)

=21x+70=25x+50

21x-25x=50-70

-4x= - 20

X=5

Now first number 3x=3*5=15

2nd number 5x =5*5=25
