Let the ratio of their present ages and ages after 5 yrs be x be x

therefore, Rajan's age is 3x and Jay's age is 2x

A/q

3x+5=4x

=5=4x-3x

therefore x=5

Now,

Rajan's present age is 3x=3*5=15

Jay's present age is 2x=2*5=10

 \boxed{GIVEN:-}

Ratio of their present ages :- 8:5

Ratio of their ages after 6yrs :- 11:8

 \boxed{FIND:-}

WE HAVE TO FIND THEIR PRESENT AGES....

 \boxed{SOLUTION:-}

let, \: their \: present \: ages \: be \: 8x,5x \\  \\ therefore \: after \: 8yrs \: there \: ages \: will \: be \: 8x + 6 ,5x + 6 \\  \\ so,8x + 6 \ratio5x + 6 = 11 \ratio8 \\  \\  \frac{8x + 6}{5x + 6}  =  \frac{11}{8}  \\ cross \: multiply \: it \\ 8(8x + 6) = 11(5x + 6) \\ now \: solve \: it \: for \: value \: of \: x  \: we \: have \\ x = 2 \\ so, \: present \: age \: jai = 8x = 8 \times 2 = 16 \\ present \: age \: of \: amy = 5x = 5 \times 2 = 10
