Answer for screen readers
The Simple Interest on ₹250 at 10% p.a. for 3 years is ₹75.
Steps to Solve
-
Calculating Simple Interest To find the Simple Interest (SI) on ₹250 at 10% per annum for 3 years, we use the formula: $$ \text{SI} = \frac{P \times R \times T}{100} $$ where ( P = 250 ), ( R = 10 ), and ( T = 3 ).
-
Substituting the values into the formula Substituting the values into the formula gives: $$ \text{SI} = \frac{250 \times 10 \times 3}{100} $$
-
Calculating the SI Calculating the above expression: $$ \text{SI} = \frac{7500}{100} = 75 $$
-
Choosing the answer Since the question asks for the SI and provides no option for ₹75, verify the values or context to see if there's been a misunderstanding or mistake.
-
Proceeding to the next question Once the first question is verified, similar calculations can be performed for questions 2–10, using appropriate formulas for each: doubling time, principal amount, compound interest, depreciation, population growth, etc.
The Simple Interest on ₹250 at 10% p.a. for 3 years is ₹75.
