As far as I know, ability to do is the correct usage and ability of doing is incorrect.

You'll find examples on the net where they have used "ability of", but that in my knowledge is incorrect.

If you encounter any sentence correction on gmat forums that has "ability of" as the right answer, then please share. I would be really glad to know.

See even there it uses "ability to distinguish" and not "ability of distinguising"

ability of + verb - ing is always wrong.. if you can find any example where they have used "ability of" + verb-ing.. and is the correct choice.. then please share..

I haven't come across any such examples.. its always "ability to do"..

You can say ability of.. but it will always be "ability of x to do y".. not like the original post "ability of doing".. thta is wrong..

ok...
thanks, i appreciate your explanations.
But my doubt was not specific to "ability". In general i find various answer choices containg " to do (activity)" and " of doing(activity)". I am not able to figure out when is what applicable. Is there any rules or is it just IDIOMS.

for eg: "gave aid to help" vs "gave aid for helping" vs "gave aid in helping"
"we went hotel to celebrate..." vs " we went to hotel for celebrating..."

Thanks DD....does it mean that
a) Ability of X doing Y = incorrect
b) Ability of X to do Y = correct

IMO it all depends on idiomatic usage....for e.g. as per my understanding only aid + in works...other usage with aid are wrong....
