Answer 1

1) Loss= Selling price - Buying price - Related costs

Loss = 25000-28000-2500

Loss= P5500

2) Buying price after discount = 875*90%

Buying price after discount = P787.50

Selling price = 15*675 = P10125

Other packets = 10*40 = P400

Total Selling price = 10125+400 = P10525

Profit = Selling price - Buying Price

Profit= 10525-787.50

Profit = 9737.50

3) Original Price = 100*650/95

Original Price = P684.20

4) Cost of mobile phone = 100*4800/120

Cost of the Mobile =P4000

5) Selling price = 85/100*5400

Selling price at a loss = P4590
