This type of problems are best solved by getting the RATE of working.
i.e. How much one man can do in one day
27 Men take 15 Day to mow 225 Hectors
27 Men in 1 Day wold mow 225/15 = 15 Hectors
1 Man in 1 Day would mow 15/27 = 5/9 Hectors
33 Men in 1 Day would mow 33 x 5/9 = 55/3 Hectors
So for 165 Hectors these 33 Men would take 165 ÷ 55/3 = 9 Days
