Re: Largest value of (x+y)
The answar is 182.818181... . When the y is 182.81818... and the x is o . We divide by the smaller number which is 11 . If we divide by the 20 or both the answar will be smaller then 182.818181... . So thats the answar .

Re: Largest value of (x+y)
$$20x+11y=2011$$
then $$11(x+y)=2011-9x$$
when $$x=1$$ then $$11(x+y)=2002$$ which is largest...
so ans:$$182$$
then $$11(x+y)=2011-9x$$
when $$x=1$$ then $$11(x+y)=2002$$ which is largest...
so ans:$$182$$
