Solution

The correct option is A $5$
Present age of Mr Ramesh and his son,
Mr Ramesh $= 4$ × $S o n$

After $10$ years their ages will be,

$R a m e s h$ + $10$ $=$ $2$ $(S o n$ $+ 10)$

Replace Ramesh with 4 x Son
4xSon $+ 10 = 2$ xSon $+ 20$

Collect like terms
4 x Son $-$ 2 x Son $= 20 - 10$
2xSon $= 10$
Son $= 5$
Mr Ramesh's son is $5$ years old.
