The ratio of two numbers are 3:5 .

If 10 is added to each number the new ratio become 5:7 .

To Find :

Smaller number .

Solution :

\longmapsto\tt{Let\:one\:first\:be=3x}⟼Letonefirstbe=3x

\longmapsto\tt{Let\:second\:number\:be=5x}⟼Letsecondnumberbe=5x

Now ,

If 10 is added to each number the new ratio become 5:7 .

\longmapsto\tt{First\:number=3x+10}⟼Firstnumber=3x+10

\longmapsto\tt{Second\:number=5x+10}⟼Secondnumber=5x+10
