Hi All,

I'm unable to solve this question & get the incorrect answer ie 18 & 1/2 days.

Question
Ahmad and Halim together took 5 days to paint their house. If Ahmad and Halim work together for 2 days, followed by Ahmad working along for 8 days, Halim will take 1 more day to complete the remaining work. How long will Ahmad take to paint the house all by himself?
Correct answer is 17 & 1/2 days.

Thanks in advance Big Grin

There are different ways to approach this sum. I prefer the model method to others.
Please see attached. Cheers

Hey (: I am also a primary 6. had my prelim and found out that the paper was actually just tricky. due to the question. you can use both of the number to become a time table then see which is similar. that#s the shorter way. Razz
