Question : An airplane goes 14 km due east and then 48 km due north. How far is it from its initial position?
Option 1: 14 km
Option 2: 48 km
Option 3: 50 km
Option 4: 28 km
Correct Answer: 50 km
Solution : By Pythagoras theorem, $(AC)^2 = (AB)^2+(BC)^2$ ⇒ $(AC)^2=(14)^2 + (48)^2$ ⇒ $(AC)^2 = 196+ 2304$ ⇒ $AC = \sqrt{2500}$ ⇒ $AC = 50\ \mathrm{km}$ Hence, the correct answer is 50 km.

Question : During a donation drive week of school, students determined to donate an average sum of Rs. 8,000 on each working day of the School, collectively (there was no holiday in the donation week except Sunday). From Monday to Friday, they collected Rs. 7,230, Rs. 6,435, Rs. 6,927, Rs. 6,855 and Rs. 6,562, respectively. How much they must collect on Saturday to meet their target?
Option 1: Rs. 6,991
Option 2: Rs. 13,991
Option 3: Rs. 6,000
Option 4: Rs. 4,991
Correct Answer: Rs. 13,991
Solution : Let the donation amount for Saturday be Rs. $x$. We know, Average = $\frac{\text{Sum of collection}}{\text{Number of days}}$ So, $8000= \frac{(7230+6435+6927+6855+6562+x)}{6}$ $\therefore x= 13991$ Hence, the correct answer is Rs. 13,991.
Question : Clouds float in the atmosphere because of their
Option 1: low pressure
Option 2: low density
Option 3: low viscosity
Option 4: low temperature
Correct Answer: low density
