    What is profit/loss & interest?

    This topic covers cost price, selling price, profit, loss, discount, and simple and compound interest.

    Why it matters

    It is the most business-relevant arithmetic in school and a staple of banking and aptitude exams.

    Key concepts you will practise

    • Profit and loss percentage on cost price
    • Marked price, discount and successive discounts
    • Simple interest: P × R × T / 100
    • Compound interest and the amount formula

    Tips that save marks

    • Profit and loss percentages are on cost price unless the question says otherwise.
    • Successive discounts do not add — apply them one after the other.
