plz give direct answer

Answer 1

Answer:

1. SP = Rs.30,000

Profit = Rs.5,000

CP = SP-profit

= Rs.(30,000-5,000) = Rs. 25,000

2. SP = Rs.30,000

Profit = Rs.5,000

CP = SP-Profit

= Rs.(30,000-5,000) = Rs.25,000

Profit percent = (Profit/CP×100)%

= (5,000/25,000×100)%

= (0.2×100)% = 20%

3. CP = Rs.4,200

Profit percentage = 30%

Profit = Profit percentage×CP

= 30%×4,200 = 30/100×4,200 = Rs.1,260

SP = CP+Profit

= Rs.(4,200+1,260)

= Rs.5,460

4. CP = $350

SP = $400

Profit = SP-CP

= $(400-350) = $50

Profit percentage = (Profit/CP×100)%

= (50/350×100)%

= (0.1428×100)% = 14.28%

5. SP = Rs.392,000

Profit percentage = 12%

CP = Rs.(SP×100)/(100-Profit percentage)

= Rs.(392,000×100)/(100+12)

= Rs.39,200,000/112

= Rs.350,000

Hope it helps.
