The simple interest on a principal amount (in ₹) is ₹318 for a period of 2 years at the rate of 6% per annum. The principal amount (in ₹) is:

Solution:

Simple Interest

( SI )=({\Principal}( P ) × {\Rate}( R ) × {\Time}( T )) \/ 100

Calculation:
We need to find the Principal (P).
Using the formula:

SI=(P × R × T) \/ 100

Substitute the given values:

\;318=(P × 6 × 2) \/ 100

\;⇒ 318=(12 P) \/ 100

\;⇒ 31800=12 P

\;⇒ P=31800 \/ 12

\;⇒ P=2650
