Question : The value of (1 + cot A – cosec A)(1 + tan A + sec A) – 1 is:

Option 1: 1

Option 2: 2

Option 3: 3

Option 4: 0

Team Careers360 5th Jan, 2024

Correct Answer: 1


Solution : $(1+ \cot A – \operatorname{cosec} A)(1 + \tan A + \sec A) – 1$
$=(1+\frac{\cos A}{\sin A}-\frac{1}{\sin A})(1+\frac{\sin A}{\cos A}+\frac{1}{\cos A})-1$
$=(\frac{\sin A+\cos A-1}{\sin A})(\frac{\cos A+\sin A+1}{\cos A})-1$
$=\frac{(\sin A+\cos A)^2-1^2}{\sin A \cos A}-1$
$=\frac{\sin ^2 A +\cos^2 A+2\sin A \cos A-1}{\sin A \cos A}-1$

Question : If A is $\frac{1}{6}$th of C, and B is twice of A, and the average of A, B, and C is 30, then the difference between A and C is:

Option 1: 40

Option 2: 60

Option 3: 50

Option 4: 80

Team Careers360 11th Jan, 2024

Correct Answer: 50


Solution : According to the question,
$A = \frac{1}{6}C$
$B = 2A=\frac{C}{3}$
Average of $n$ observations $=\frac{\text{Sum of all observations}}{n}$
Average $=\frac{A+B+C}{3} = \frac{\frac{C}{6} +\frac{C}{3} +C}{3}$
$⇒ 30 = \frac{\frac{9C}{6}}{3}$
$⇒ 30 = \frac{C}{2}$
$\therefore C = 60$
Also,
