Profit, Loss and Discount
The chapter Profit, Loss and Discount is a crucial part of commercial mathematics in Class 7 ICSE. It bridges classroom learning with real-world financial transactions, teaching students how businesses calculate earnings, incur losses, and offer price reductions. You will learn to find Cost Price (CP), Selling Price (SP), Marked Price (MP), and convert them into percentages. This chapter carries significant weight in ICSE board and school examinations, typically appearing in both short calculation formats and multi-step word problems. Mastery of these concepts builds a strong foundation for future topics like simple interest, compound interest, and higher-level commercial arithmetic.

Cost Price (CP)
The price at which an article is purchased by a shopkeeper or individual, sometimes including additional expenses like overheads or transportation.
Selling Price (SP)
The final price at which an article is sold to the customer after all calculations of profit, loss, or discount.
Profit and Loss
Profit occurs when Selling Price is greater than Cost Price (SP > CP), whereas Loss occurs when Cost Price is greater than Selling Price (CP > SP).
Marked Price (MP) and Discount
Marked Price is the labeled price of an item, and Discount is the reduction offered on this marked price to attract buyers.
Overhead Charges
Additional expenses incurred on a purchased item, such as repair costs or cartage, which must be added to the Cost Price.

Frequently Asked Questions
Is profit or loss percentage always calculated on the Cost Price?
Yes, unless stated otherwise in the question, profit and loss percentages are always calculated with respect to the Cost Price (CP).
On what price is the discount percentage calculated?
Discount percentage is always calculated on the Marked Price (MP), which is the printed price of the article, never on the Cost Price.
What should I do if a question mentions repair costs or transportation charges?
These are overhead charges and must be added to the original Cost Price to find the total effective Cost Price before calculating profit or loss.
