⚠Here's your answer⚠

Let the present age of Ranjan and Jay is be 3x and 2x

After 5 years

According to question

 \frac{3x + 5}{2x + 5}  =  \frac{4}{3}  \\  \\ 3(3x + 5) = 4(2x + 5) \\  \\ 9x + 15 = 8x + 20 \\  \\ 9x - 8x = 20 - 15 \\  \\ x = 5

SO The present ages of Ranjan and Jay is 15 and 10 years...

Hope it helps ....

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
