okay..if there happened to be some erratum in the question, i am really sorry about that, maybe the answer was predicted to be some sort of approximation to a whole number..but would you please explain on how you ended up getting 22:21..i just wanted to know clearly how it is possible to have ratio from unequal two separate number of days
I'm happy to answer this. :-)

The question asks for "the ratio of rate of earning $2.75 for 5 days' work to the rate of earning $2.1 for 4 days' work" ----- it's asking for a ratio of rates, which is a very difficult idea.

Rate #1 = $2.75/5 = $0.55

Rate #2 = $2.10/4 = $1.05/2

The ratio sought by the question is the ratio of these two rates:

ratio = [Rate #1]/[Rate #2] = ($0.55)/[$1.05/2] = ($0.55)*(2/$1.05) = $1.10/$1.05 = 110/105 = 22/21

Does all this make sense?

Mike :-)
