Answer
Explanation
S.I. $=₹ 210, R=3 \frac{3}{4} \%=\frac{15}{4} \%, T=2 \frac{1}{3} \mathrm{yrs}=\frac{7}{3} \mathrm{yrs}$. $$\therefore \quad \text { Sum }=₹\left(\frac{100 \times 210}{\frac{15}{4} \times \frac{7}{3}}\right)=₹\left(\frac{100 \times 210 \times 4 \times 3}{15 \times 7}\right)=₹ 2400 .$$
