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 : If $\sin7x=\cos11x$, then the value of $\tan9x+\cot9x$ is:
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 2
Solution : We know that $\sin(90° - \theta) = \cos\theta$ $\sin7x = \cos11x$ $⇒\sin7x = \sin (90° - 11x)$ $⇒7x = 90° - 11x$ $⇒18x = 90°$ $⇒x = 5°$ Substituting $x = 5°$ in $\tan9x+\cot9x$, $\therefore\tan45° + \cot45°=1 + 1= 2$ Hence, the correct answer is
