Must give the working and the answer!!

Maybe your question something wrong. Try rephrase your question.Originally posted by jiaweiwei87:sorry the answer is Wrong
i only want the working, this working is correct thankOriginally posted by Uncertain:lol primary school math... TS primary school one
First, we need to know the fraction of $$$ left
1 - 1/2 - 1/3(1/2) - 1/4(1/3)(1/2) = 1 - 1/2 - 1/6 - 1/24 = 7/24
7/24 units = 7777
1 whole = 24/7 x 7777 = $26664
1 year = 26664
1 month = 1/12 x 26664 = $2222 (ans)
Next time, post this in homework forum
