Question

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

Answer 1

Answer:

1st no is 15, 2nd no is 25

Step-by-step explanation:

let the no.s be 3x and 5x respectively,

as per condition,

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

cross multiplying we get,

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

25x+50 = 21x+70

25x-21x = 70-50

4x = 20

x = 20/4

x = 5

putting value of x in 3x and 5x we get,

15 and 25.. hence the numbers are 15 and 25..

hope it helps..
