Correct Answer: $60^{\circ}$

Solution :

Given that $AE:ED=5:1$, $\angle BAD=30^{\circ}$ and $\tan \left ( \angle ACB \right )=6\tan \left ( \angle DBE \right )$
Let $AE$ and $ED$ be $5x,x$.
So, $DE=x, AE=5x$ and $AD=6x$
In $\triangle ABD$,
$\angle ABD+\angle BAD=90^{\circ}$
⇒ $\angle ABD =90^{\circ}-\angle BAD$
⇒ $\angle ABD =90^{\circ}-30^{\circ}=60^{\circ}$

Correct Answer: 60 metres

Solution :
AB = transparent water surface then according to question,
$\triangle$CPM = 30°; $\angle$C'PM = 60°
CM = $h$
CB = Height of the aeroplane from the water surface of the lake = $h + 30$
$\therefore$ C'B = $h + 30$
In $\triangle$CMP, tan

Correct Answer: 457.1

Solution : Given:
Production of cement by company C in 2018 = 350 million tonnes
Production of cement by company C in 2019 = 400 million tonnes
Now,
Percentage increase of production from 2018 to 2019 = $\frac{400\ -\ 350}{350}\times 100= 14.28\%$
Production of cement by company
