two numbers are in the ratio 1:2. If 7 is added to both, their ratio changes to
3:5. Find the greatest number​

Answer 1

Answer:

Let the ratio be x

So, two numbers are x and 2x

If 7 is added to both

one number = x+7

other number = 2x +7

But, their ratio changes to 3: 5

According to the question

x+7/2x+7 = 3/5

5x+ 35 = 6x + 21

35 -21 =6x- 5x

14 = x

Hence,the greatest number us 28
