Question : A conical vessel (solid) is made of iron. Its base radius is 7 cm and its height is 15 cm. If the weight of the iron per cubic centimetre is 15 g, what is the weight of the vessel?
Option 1: 13.55 kg
Option 2: 12.55 kg
Option 3: 14.55 kg
Option 4: 11.55 kg
Correct Answer: 11.55 kg
Solution : Base radius of conical vessel = 7 cm Height of conical vessel = 15 cm Weight of the iron per cubic centimetre (density) = 15 g Volume of the Conical Vessel = $\frac{1}3\pi r^2h$ = $\frac{1}3\pi \times 7^2\times 15=770$ cm3 Weight of vessel

Question : A balloon leaves from point P and rises at a uniform speed. After 6 minutes, an observer situated at a distance of $450\sqrt3$ metres from point P observes that the angle of elevation of the balloon is 60°. Assume that the point of observation and point P is on the same level. What is the speed (in m/s) of the balloon?
Option 1: 4.25
Option 2: 3.75
Option 3: 4.5
Option 4: 3.45
Correct Answer: 3.75
Solution : Given: Distance between the observer and the point P is $450\sqrt{3}$ m. After 6 minutes angle of elevation is 60°. So, $\tan\theta = \frac{\text{Perpendicular}}{\text{Base}}$ $⇒\tan 60° = \frac{H}{450 \sqrt{3}}$ $⇒\sqrt{3} = \frac{H}{450 \sqrt{3}}$ $\therefore H =450×3 = 1350$ m Now, for the speed of the
Question : The disease that is caused by virus is
Option 1: Typhoid
Option 2: Cholera

Question : The average of 25 numbers is 64. The averages of the first 13 numbers and that of the last 13 numbers are 62.8 and 72.2, respectively. If the $12^{\text {th }}$ number is 61, and if the $12^{\text {th }}$ and $13^{\text {th }}$ numbers are excluded, then what is the average of the remaining numbers (correct to one decimal place)?
Option 1: 59.2
Option 2: 62.2
Option 3: 60.2
Option 4: 61.5
Correct Answer: 60.2
Solution : Sum of the 25 numbers = 64 × 25 = 1600 Sum of the first 13 numbers = 13 × 62.8 = 816.4 Sum of the last 13 numbers = 13 × 72.2 = 938.6 Number 13th = (Sum of the first 13 numbers +
Question : Directions: If A means –, C means ×, D means ÷, and E means +, then 14 C 3 A 12 E 4 D 2 = ?
Option 1: 6
Option 2: 17
Option 3: 28
Option 4: 32
Correct Answer: 32
Solution : Given: 14 C 3 A 12 E 4 D 2 = ?
After replacing the letters with mathematical signs, the equation becomes – = 14 × 3 –12 + 4 ÷ 2 = 14 × 3 –12 + 2 = 42 –12 + 2 =
Question : Directions: In the following question, some parts of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select "No Error."
