Question : The given pie chart shows the percentage distribution of 450 employees in an organisation. Read the pie chart and answer the question that follows.
What is the central angle of the sector representing the number of employees in department E?
Option 1: $36^\circ$
Option 2: $108^\circ$
Option 3: $72^\circ$
Option 4: $90^\circ$
Correct Answer: $72^\circ$
Solution : Number of employees in department E = 20% Central angle = $\frac{\text{percentage of employees in department E}}{100}\times360^\circ$ = $\frac{20}{100}\times360^\circ$ = $72^\circ$ Hence, the correct answer is $72^\circ$.

Question : A hemispherical bowl of radius 30 cm is filled with water by using a cylindrical glass. If the water from the cylindrical glass is poured 72 times to fill the bowl completely and the height of the glass is 10 cm, then what is the base radius of the cylindrical glass?
Option 1: 7.5 cm
Option 2: 8 cm
Option 3: 5 cm
Option 4: 6 cm
Correct Answer: 5 cm
Solution : The volume of a hemisphere $ = \frac{2}{3}\pi r^3$ The volume of a cylinder $ = \pi r^2 h$ Where $r$ is the base radius and $h$ is the height. Given that the radius of the hemisphere is 30 cm and the height of
Question : Q is a point in the interior of a rectangle ABCD. If QA = 3 cm, QB = 4 cm and QC = 5 cm, then the length of QD (in cm) is:
Option 1: $3\sqrt2$
Option 2: $5\sqrt2$
Option 3: $\sqrt{34}$
Option 4: $\sqrt{41}$
Correct Answer: $3\sqrt2$
Solution : According to the question, we draw a figure of a rectangle ABCD. Given that: QA = 3 cm, QB = 4 cm and QC = 5 cm QD2 + QB2 = QA2 + QC2 ⇒ QD2 + 16 = 9
