1965 to 1995 or 30 yrs, - - - - Gains 30*2 = 60 lb
1995 to 2010 or 15 yrs, - - - - Gains 15*2 = 30 lb
Now, 40% is equivalent to 60 lb
Then, 100% is equivalent to 60*100/40 = 150 lb
That is, in 1965 his weight was 150 lb;
So, in 1995 = 150 + 60 = 210 lb;
And in 2010 = 210 + 30 = 240 lb
Required percent = (210/240)*100 = 87.5% (Ans.)
