let the nos be 3x and 5x
ATq
 \frac{3x-5}{5x-5}= \frac{1}{2}
⇒2(3x-5)=5x-5
⇒6x-10=5x-5
⇒x=5
so the nos are 15 and 25

let,

the two numbers in the ratio 3:5 be 3x and 5x

⇒3x/5x

5 is subtracted from each number they will become in the ratio 1:2

⇒3x-5/5x-5=1/2

⇒2(3x-5)=5x-5

⇒6x-10=5x-5

⇒6x-5x=10-5

⇒x=5

sub x value in 3x and 5x

we get  3(5)=15

             5(5)=25

therefore the two numbers are 15 and 25
