Question

8. Two numbers are such that the ratio between them is 3 : 5. If each is increased by 10, the
ratio between the new numbers so formed is 5 : 7. Find the original numbers.​

Answer 1

Answer:

first no. = 15

Second no. =25

Step-by-step explanation:

let the ratio’s no be x

Then the no. Are : 3x and 5x

—-Increasing by 10

3x +10

5x + 10 ——then their ratio is 5:7

So

3x +10 / 5x +10 = 5/7

21x + 70 = 25x + 50

20 = 4x

5 = x

So the no. Are

3x = 3*x = 3*5 = 15

5x = 5*x = 5*5 = 25
