Question

two number are such that the ratio between them is 5 : 7. if 7 is added to each of them the ratio becomes 3 : 4 find the numbers.​

Answer 1

Answer:

35 and 49

Step-by-step explanation:

Ratio = 5:7

If 7 is added then the ratio becomes 3:4

So

5x + 7/7x = 3/4

On cross multiplication we get

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

20x + 28 = 21x + 21

28 - 21 = x

x = 7

Then the numbers are

5 × 7 = 35

7 × 7 = 40
