Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 2,992

SI = 8085 − 6300 = ₹1785

Time = 10/3​ years

R=SI×100P×T=1785×1006300×103=17850021000=8.5%R = \frac{SI \times 100}{P \times T} = \frac{1785 \times 100}{6300 \times \frac{10}{3}} = \frac{178500}{21000} = 8.5\% \\[10pt]

SI  =8000×8.5×225100=8000×187500=1496000500=₹2992 = \frac{8000 \times 8.5 \times \frac{22}{5}}{100} = \frac{8000 \times 187}{500} = \frac{1496000}{500} = ₹2992
