Question : The rate of simple interest for which INR 9,000 will amount to INR 10,200 in 4 years is:
Option 1: $4\frac{2}{3}\%$
Option 2: $7\frac{1}{3}\%$
Option 3: $5\frac{1}{2}\%$
Option 4: $3\frac{1}{3}\%$
Correct Answer: $3\frac{1}{3}\%$
Solution : Simple interest = 10,200 – 9,000 = 1,200 Simple Interest $=\frac{\text{Principal×Rate×Time}}{100}$ ⇒ $\text{Rate} = \frac{1200 \times 100}{4\times 9000}$ ⇒ $\text{Rate} = \frac{120}{4\times 9}$ ⇒ $\text{Rate} = \frac{10}{3}$ ⇒ $\text{Rate} = 3\frac{1}{3}\%$ Hence, the correct answer is $3\frac{1}{3}\%$.
Question : A car travels from A to B at the rate of 40 km/h and returns from B to A at the rate of 60 km/h. Its average speed during the whole journey is:
Option 1: 48 km/h
