Calculate the approximate simple interest on ₹73,000 at $$13\frac{1}{3}$$​% per annum for 10 months.

Correct option is B

Given:
Principal amount ( P ) = ₹73,000.
Rate of interest ( R ) =$$13 \frac{1}{3} \%$$ per annum = $$\frac{40}{3} \%$$​ per annum.

Time ( T ) = 10 months =$$\frac{10}{12}$$ years = $$\frac{5}{6}$$​  years.
Formula Used:
Simple Interest ( SI )= $$\frac{P \times R \times T}{100}$$​​
Solution:
R =$$13 \frac{1}{3} \% = \frac{40}{3} \%$$​​
T =$$10 \, \text{months} = \frac{10}{12} \, \text{years} = \frac{5}{6} \, \text{years}$$​​

SI =$$\frac{P \times R \times T}{100} = \frac{73000 \times \frac{40}{3} \times \frac{5}{6}}{100}$$​​

SI = $$\frac{73000 \times 40 \times 5}{3 \times 6 \times 100}$$​

SI $$= \frac{73000 \times 200}{1800}$$​

SI =$$\frac{14600000}{1800} \approx 8111$$​​
