(1) The cost of each DVD recorder is $80000/50 = $1600

The marked selling price = $1600 * (1 + 25%) = $2000

Total sales for 35 recorders = 35 * $2000 = $70000

The selling price of the remaining (50 - 35) = 15 recorders is

$2000 * 30% = $600

Total sales for these 15 recorders = 15 * $600 = $9000

Therefore total sales = 70000 + 9000 = $79000

Loss = $80000 - $79000 = $1000

Loss percentage = 1000/80000 * 100% = 1.25%

(2) Since the marked price of $216 has 25% profit, the cost of the watch is

$216 / (1 + 25%)

= $172.8

Total cost of 80 watches = 80 * $172.8 = $13,824

Sales of all 80 watches = 65 * $216 + 15 * $180 = $16,740

Profit = 16740 - 13824 = $2916

Profit percentage = 2916 / 13824 * 100% = 21 & 3/32 %
