Important Formulas for IPMAT Interest Questions
You only need a few basic formulas to solve most interest questions in IPMAT. These formulas help you find simple interest, compound interest, principal, amount, rate, and time.
You can download the full formula PDF from the link above. Here is a quick look at some of the main ones:
Concept | Formula |
Simple Interest | (P × R × T) / 100 |
Amount in Simple Interest | P + SI |
Compound Amount | P(1 + R/100)^T |
Compound Interest | Amount - Principal |
Principal | (SI × 100) / (R × T) |
Rate | (SI × 100) / (P × T) |
Time | (SI × 100) / (P × R) |
These formulas are useful for solving questions on simple interest, compound interest, annual growth, and other money-based problems that often appear in IPMAT.
