Profit and Loss | GRE Quant

Profit and loss explain whether a transaction creates a gain or a loss and the exact extent of that change, forming a strong base for arithmetic situations built around buying and selling. From this base, GRE Quant designs layered questions and word problems that reward precise tracking of value as it flows through each stage of a transaction. The following video breaks profit and loss into a smooth, logical sequence, walks through cost price, markup, marked price, discount, selling price, profit, loss, profit percentage, and profit margin, and then applies the full framework to GRE style questions so the entire process feels connected, efficient, and rewarding to use

Key Slide Recap

Simple and Compound Interest | GRE Quant

Simple and compound interest show how an amount grows over time through interest, where simple interest builds only on the original amount and compound interest builds on both the original amount and accumulated interest. These ideas power many GRE Quant questions and word problems that reward clear tracking of time based change and accurate reading of given details. The following video presents simple and compound interest in a smooth and engaging flow, explains principal, rate, time, interest earned, and total amount, highlights the difference between simple growth and compounded growth across periods, and then applies the approach to GRE style questions so the process feels clear, efficient, and exciting to use.
