What must be subtracted from each term of the ratio 3:7 so that the ratio becomes 2:5?
My attempt: Let two numbers be 3x and 7x. So, 3x−y7x−y=25⟹15x−5y=14x−2y⟹y=x3. But the answer is given as 13 only.
I wish somebody could provide some clarifications.
The constant of proportionality is 18.
Hope this helps!
