To find the number of units at hand as of July 30, we need to calculate the total number of units purchased and returned, and then subtract the total number of units sold. Total units purchased = 200 + 200 + 200 = 600 units Total units returned = 80 units Total units sold = 160 + 180 + 120 + 100 = 560 units Therefore, the units at hand as of July 30 can be calculated as follows: Units at hand = Closing stock + Total units purchased - Total units returned - Total units sold Units at hand = 100 + 600 - 80 - 560 Units at hand = 60 Therefore, the answer is 60 units.
