Answer Posted / vignesh1988i
it's simple ,
the age of the father is 32 and the son is 12.... here no
need of equation just mental calculation is enough.........
here the son after 3 yrs will be 3/7 times of the dad... so
the age of the father MUST BE DIVISIBLE BY 7.. AT THE SAME
TIME NEXT INFO. IS BEFORE 10 yrs ,the ratio is 1:5..
therefore both of the ages must be divisible by 7,5... so
taking 35 as the age of father , SINCE THE FIRST NUMBER
THAT IS BOTH DIVISIBLE BY BOTH 7 & 5 IS 35.... so son's age
will be 15.... then subtract 10 yrs from that, they will be
5:25 , so the ratio will come as 1:5.... therefore the
present age of father and son is (35-3)=32 , (15-3)=12
respectively................
thank u
