Answer: 15 and 25

Step by step explanation:

let the numbers be 3x and 5x.

According to question:

3x-5/5x-5=1/2

2(3x-5)=1(5x-5) (by cross division)

6x-10=5x-5

6x-5x= -5+10

x=5

The numbers are 3x=3*5=15 and 5x=5*5=25.

Answer 2

Answer:

15 and 25

Step-by-step explanation:

Since the ration of two numbers is 3:5, let the numbers be 3x and 5x.

now both the numbers are subtracted from 5 and the ratio of number becomes 1:2 i.e.

•(3x-5)/(5x-5)=1/2

cross multiplying and solving the equation for x

we get x=5

therefore the numbers were 15 and 25
