Question : If $\frac{\sin ^2 \theta}{\cos ^2 \theta-3 \cos \theta+2}=1, \theta$ lies in the first quadrant, then the value of $\frac{\tan ^2 \frac{\theta}{2}+\sin ^2 \frac{\theta}{2}}{\tan \theta+\sin \theta}$ is:
Option 1: $\frac{2 \sqrt{3}}{27}$
Option 2: $\frac{5 \sqrt{3}}{27}$
Option 3: $\frac{2 \sqrt{3}}{9}$
Option 4: $\frac{7 \sqrt{3}}{54}$
Correct Answer: $\frac{7 \sqrt{3}}{54}$
Solution : Given that $\frac{\sin ^2 \theta}{\cos ^2 \theta-3 \cos \theta+2}=1$, $⇒\sin ^2 \theta = \cos ^2 \theta-3 \cos \theta+2$ $⇒\cos ^2 \theta - \sin ^2 \theta - 3 \cos \theta + 2 = 0$ Since $\cos ^2 \theta = 1 - \sin ^2 \theta$, $⇒1

Question : Directions: If A stands for +, B stands for –, and C stands for ×, then what is the value of (10 C 4) A (4 C 4) B 6 = ?
Option 1: 46
Option 2: 50
Option 3: 56
Option 4: 60
Correct Answer: 50
Solution : Given: (10 C 4) A (4 C 4) B 6 = ?
After replacing the letters with mathematical signs, the equation becomes – = (10 × 4) + (4 × 4) – 6 = 40 + 16 – 6 = 56 – 6 = 50
Question : In an examination, 73% of the candidates passed the quantitative aptitude test, 70% passed the general awareness test, and 64% passed both. If 6300 failed in both subjects, the total number of examinees was:

Option 2: 50000
Option 3: 30000
Option 4: 25000
Correct Answer: 30000
Solution : Given: Passed the quantitative aptitude test = 73% Passed the general awareness test = 70% Passed in both subjects = 64% Failed in both subjects = 6300 Total candidates = 100% Percentage of candidates who passed in at least one subject = 73% + 70%

Option 3: The sum of two sides is always greater than the third side.
Option 4: The sum of two sides is always less than the third side.
Correct Answer: The sum of two sides is always greater than the third side.
Solution : In a triangle, the sum of two sides is always greater than the third. Hence, the correct answer is 'The sum of two sides is always greater than the third side'.
