Incomplete record

If they add 50% to the cost, then for every $100 cost they add a profit of $50 giving a selling price of $150. Putting it the other way round, for every 150 selling price the cost is 100. So if the sales as 281,250 then the cost of sales must be 100/150 x 281,250. (100/150 is the same as 2/3) I do not know what you mean by 'qno' but I work through many examples like this in my free lectures on mark-ups and margins. The lectures are a complete free course for Paper FA and cover everything needed to be able to pass the exam well.

A business's bank balance increased by $750,000 during its last financial year. During the same period it issued shares of $1 million and repaid a loan note of $750,000. It purchased non-current assets for $200,000 and charged depreciation of $100,000. Working capital (other than the bank balance) increased by $575,000. What was its profit for the year? i don understand why current asset is not decreased. when purchased non-current asset?

This question is testing Statements of Cash Flows. We know the change in the bank balance and therefore you can work backwards in order to calculate the chad flow generated from operations, and from there you can calculate the profit for the year :-)
