Question

If two numbers are in the ratio 5 : 7 and if

5 is added to each of them, the ratio
becomes 3 : 4. Find the numbers.​

Answer 1

25 and 35

Explanation:

Let the numbers be 5x and 7x

(5x+5)/(7x+5)=3/4

4(5x+5)=3(7x+5)

20x+20=21x +15

20-15=21x-20x

5=x

So,the numbers will be

5x=5*5 =25

7x=7*5=35
