-- Mr. A. can complete the job in 12 days.
-- He does 1/12 of the job in 1 day.
-- Mr. B. is 60% as efficient as Mr. A. is.
-- Mr. B. does (60% of 1/12) = 0.6/12 = 1/20 of the job in 1 day.
-- It takes Mr. B. 20 days to do the same work.

Q can do the work in 6 days. ( Time taken by P will be more than Q i.e their time ratio will be 150:100 and this is to 9:x, or 150:100::9:X which will give value of X as 6)
