Question

Two numbers are in the ratio 3 : 5. If each number is increased by 10, the
resultant numbers are in the ratio 5:7. Find the original numbers.​

Answer 1

Step-by-step explanation:

Let the number be 3x and 5x

If each number is increased by 10 then

3x+10;5x+10 = 5 : 7

5(5x+10)=7(3x+10)

25x+50=21x+70

4x=20,x=5

Therefore, The numbers are 3×5=15

and 5×5=25
