Correct Answer: $7$

Solution : Given: $\frac{28}{21} \times \frac{96}{4} \div \frac{125}{5} \times \frac{42}{192}+\frac{297}{125} \times \frac{875}{3} \div \frac{99}{4} \times \frac{6}{25}$
= $\frac{\frac{4}{3} × \frac{96}{4}}{\frac{125}{5}}$ × $\frac{42}{192}$ + $\frac{\frac{297}{125}×\frac{875}{3}}{\frac{99}{4}}$ × $\frac{6}{25}$
= $\frac{\frac{4}{3} × 24}{\frac{125}{5}}$ × $\frac{42}{192}$ + $\frac{\frac{297}{125}×\frac{875}{3}}{\frac{99}{4}}$ × $\frac{6}{25}$
= $\frac{ 32}{25}$ × $\frac{7}{32}$ + $\frac{\frac{297}{125}×\frac{875}{3}}{\frac{99}{4}}$ × $\frac{6}{25}$
= $\frac{

Correct Answer: 200 m/sec

Solution :
Height of the aeroplane = BD = CE = $1500\sqrt{3}$ m and $\angle$ BAE = 60°, $\angle$ CAE = 30°
In $\Delta$ ADB,
$\tan 60°=\frac{1500\sqrt{3}}{AD}$
⇒ $\sqrt{3}=\frac{1500\sqrt{3}}{AD}$
⇒ AD = $\frac{1500\sqrt{3}}{\sqrt{3}}$
⇒ AD = 1500 m
In $\Delta$ CAE,
$\tan 30°=\frac{1500\sqrt{3}}{AE}$
⇒ $\frac{1}{\sqrt{3}}=\frac{1500\sqrt{3}}{AE}$
⇒
