Question

By selling a wall clock at a loss of 20%, a shopkeeper incurs a loss of 80. Find its cost price and selling price . answer fast and it should be a ful explanation and the cost price should be 400 and selling price 320 ​

Answer 1

Answer:

we will do calculations for each clock separately

for clock on which there was profit of 20%

The Selling Price is 240

in percentage terms

CP + Profit = SP (240)

100% + 20% = 120% ( assuming 20% profit is on cost price)

hence, SP = 120% = 240

so Profit= 20*240/120=40

Profit =40

Let calculate loss on clock on which loss was 20%

The Selling Price is 240

in percentage terms

CP - Loss = SP (240)

100% - 20% = 80% ( assuming 20% loss is on cost price)

hence, SP = 80% = 240

so Loss = 20*240/80 =60

Loss = 60

Hence, Total Profit or Loss = Profit of 40 minus Loss of 60

Total Loss = 20
