Question

Ratio of two number are 3:5 and we add 10 to them ratio will become 5:7 find the numbers​

Answer 1

Answer:

Step-by-step explanation:

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

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

21x+70=25x+50

25x-21x=70-50

4x=20

x=5

Numbers are 3*4=12

5*4=20

Answer 2

Step-by-step explanation:

x/y = 3/5

x= 3y/5

x+10/y+10 = 5/7

3y/5+10/y+10 = 5/7

7(3y+50/5) = 5(y+10)

21y+350/5 = 5y+50

21y/5-5y = 50-350/5

21y-25y/5 = 250-350/5

-4y = -100

y = 25

x = 3y/5 = 3*25/5 = 3*5 = 15

x = 15

y = 25
