Answer 2

Step-by-step explanation:

let the two numbers be '3x' and '5x'

each on increasing 10 gives the ratio of 5 : 7

3x + 10 : 5x + 10 = 5 : 7

product of means = product of extremes

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

25x + 50 = 21x + 70

25x - 21x = 70 - 50

4x = 20

x = 20/4

x = 5

the original numbers 3x = 3(5) = 15

and 5x = 5(5) = 25
