Answer 1

Answer:

_____________________

find the loss or profit percent

_____________________

1. cp = $4000 and profit = $40

formula to find profit in percentage

= profit/cp x 100

40/4000 x 100

40 / 40 x 1

4/4 = 1%

_____________________

2. sp = $1272 and loss = $328

so in this we have to find cp

cp = 1272+328=$1600

328/1600 x 100

328/16 = 20.5%

_____________________

3. sp = $1820 and profit $420

finding cp

cp = 1820 - 420 = $1400

420/1400 x 100

420/14 = 30%
