Profit and loss is 2–3 direct questions in SSC CGL and appears inside DI too. These tricks solve most questions mentally.

Formulas

• Profit = SP − CP; Profit% = Profit × 100/CP (always on CP)
• SP = CP(100 + P%)/100; CP = SP × 100/(100 + P%)
• Discount is on Marked Price: SP = MP(100 − D%)/100
• Successive discounts a%, b%: net = a + b − ab/100
• Two items sold at same SP, one at x% profit and other x% loss → net loss = x²/100 %

Solved questions
