Question

two numbers are in the ratio 3:5. if 25 is added to first number and 25 is subtracted from the second number.then the resulting numbers bear the ratio 2:3.find the orignal number​

Answer 1

Answer:let the common factor be x.

Therefore ,the ratio be 3x:5x

3x+25/5x-25=2:3

3(3x+25)=2(5x-25)

9x+75=10x-50

9x-10x=-50-75

-x=-125

x=125

Therefore, the original numbers are 3x=3*125=375

5x=5*125=625
