Learn the shortcut first
Shortcut before you solve
Simple Interest is direct once principal, rate and time are identified.
Featured shortcut
Use SI = P x R x T / 100 after confirming that interest is calculated only on the original principal.
Exam-use rule
Simple interest is calculated on the original principal throughout the period.
Use this in 3 seconds
Identify P, R and T, then substitute directly into PRT/100.
Faster solving steps
Use this 4-step method before solving to keep your thinking fast and repeatable.
Step 1
Identify relation
Spot the pattern, relationship, or core idea first.
Step 2
Apply same pattern
Use the same rule instead of re-solving from scratch.
Step 3
Eliminate wrong options
Remove confusing choices before comparing the last few.
Step 4
Confirm final answer
Pick the option that matches the shortcut most cleanly.

Use SI = P x R x T / 100 after confirming that interest is calculated only on the original principal.
Tip: Simple interest adds the same interest amount for each equal time period when rate and principal stay constant.
Real exam shortcut before you solve
Find the simple interest on Rs. 1000 at 10% per annum for 2 years.
Step 1
Use SI = P x R x T / 100.
Step 2
SI = 1000 x 10 x 2 / 100 = Rs. 200.
Rule
Simple interest is calculated on the original principal throughout the period.
3-second trick
Identify P, R and T, then substitute directly into PRT/100.
Trap to avoid
Do not compound previous interest into the principal.
Correct answer
Rs. 200
Worked example
Find the simple interest on Rs. 1000 at 10% per annum for 2 years.
Thinking path
- Principal = 1000.
- Rate = 10% per annum.
- Time = 2 years.
- Interest = 200.
Final answer: Rs. 200
Why this is fast: The direct PRT/100 formula gives SI in one line.
