Question : Let A and B be two cylinders such that the capacity of A is the same as that of B. The ratio of the diameters of A and B is 1 : 4. What is the ratio of the heights of A and B?
Option 1: 16 : 1
Option 2: 16 : 3
Option 3: 3 : 16
Option 4: 1 : 16
Correct Answer: 16 : 1
Solution : Capacity of cylinder A = Capacity of cylinder B The ratio of the diameters of A and B = 1 : 4 ⇒ $\frac{r_1}{r_2} = \frac{1}{4}$ ⇒ $r_2 = 4r_1$ Let $h_1$ and $h_2$ be the heights of cylinders. The volume of the

Question : The base of a triangle is $12\sqrt{3}$ cm and two angles at the base are 30° and 60°, respectively. The altitude of the triangle is:
Option 1: $12$ cm
Option 2: $6$ cm
Option 3: $10\sqrt{3}$ cm
Option 4: $9$ cm
Correct Answer: $9$ cm
Solution : Let BD be $x$ cm. $\therefore$ CD =$ (12\sqrt{3} - x) $cm. $\angle$ADB = $\angle$ADC = 90° From $\triangle$ ABD, $\tan 30°=\frac{AD}{BD}$ $⇒\frac{1}{\sqrt{3}}=\frac{AD}{x}$ So, AD = $\frac{x}{\sqrt{3}}$-----------(1) From $\triangle$ACD, $\tan 60°=\frac{AD}{CD}$ $⇒\sqrt{3}=\frac{AD}{ (12\sqrt{3} - x)}$ So, AD = $\sqrt{3}(12\sqrt{3}-x)$----------(2) From 1 and 2, we
