Madhya Pradesh Police Exam Model Paper 9

Given:
Marked price of jeans = Rs. 3000
Discount% = 20%
Profit% = 20%
Formula used:
SP = MP × (100 - D%)/100
CP = SP × 100/(100 + P%)
SP is selling price, CP is cost price, D% is discount percent, P% is profit percent
Calculation:
SP of jeans =3000×(100−20)/100
⇒ SP = 2400
CP =2400×100/(100+20)
⇒ CP =2400×(10/12)=2000
MP × (100 - D%)/100 = CP × (100 + P%)/100
3000×80/100=CP×120/100
CP =24000/12=Rs2000
∴ Cost price of the pair of jeans is Rs. 2000
