Let ronit's present age be x

the father's age will be =x+3x=4x

after \:  8  \: years-4x+8= \frac{5}{2} (x+8)


3x=24

x=8

Therefore , required \:  ratio \:  is  \: 4x+ \frac{16}{x} +16=  \frac{48}{2} =2


so option A is correct!

let Ronit age is x then father age = 3x + Ronit age = 3x + x = 4x
after 8 years Ronit age = (x+8) , Father age= (4x+8)
(4x+8)=5/2(x+8) so 8x+16=5x+40
3x=24 or x = 8
so Father age = 4x = 32 , son age = 8
after 8 year Father age = 32+8=40 , son age=8+8=16
after 8 more year
Father age = 48
Son age = 24
so now age is 2 times of Ronit's age.
