Sales in units ?
Ending finished goods inventory in units ?
Sales in dollars $1,300,000
Cost:
Direct labor $90,000

The question is to find the selling cost per unit and the units sold...

Sometimes the easiest way to get missing figures when working with those inventory accounts is making a t account for each one, inserting the numbers given, then working backwards to find the missing numbers. You need to know the flow of accounts. If you're not sure of that, there's some material here:
Principles of Accounting Chapter 19 (http://www.principlesofaccounting.com/chapter%2019.htm#TRACKING%20JOB%20COSTS%20IN%20THE %20CORPORATE%20LEDGER)

Cost of Production Calculation
RM 480,000
Labour 90,000
Mfg OH 300,000
Sel & Admin OH 380,000

COP 1,250,000
Selling cost per Unit 43.10


No. of Units sold should be 29,000 only as there is no opening or closing stock.

See the post above yours, the one with the link to the homework guidelines that say we aren't here to do people's homework for them. It's even worse when you don't show work so someone can learn something from it at least.

Not to mention the answer is incorrect. Been seeing a lot of that today - people doing other people's homework for them, and then doing it incorrectly. Hopefully they'll learn a lesson about taking just answers from people when they start getting it wrong.

Units sold can not be calculated until the selling price per unit is given. Based on the units sold it is easy to calculate ending inventory of finished goods.
