Two numbers are in the ratio
3:5. If each number is increased
by 10, then the ratio becomes
5:7, The numbers are​

Answer 1

Answer:

Step-by-step explanation:

Let the two numbers be 3x and 5x.

When the numbers are increased by 10, they are (3x + 10) and (5x + 10)

Let the ratio after being increased by 10 be 5x and 7x

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

8x + 20 = 12x

20 = 12x - 8x

20 = 4x

20/4 = x

5 = x

Therefore, the numbers are 3x = 3 x 5 = 15 and 5x = 5 x 5 = 25

And when increased by 10, are 25 and 35.

Answer 2

Answer:

let the no. be 3x and 5x

as per the question

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

because it is in ratio form

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

21x+70 =25x+50

70-50=25x -21x

20=4x

x=20/4

x=5
