Correct Answer: $\cos A$

Solution : Consider, $\operatorname{cosec} A+\cot A=a \sqrt{b}$
Squaring both sides, we get,
⇒ $(\operatorname{cosec} A+\cot A)^2=a^2b$
⇒ $\operatorname{cosec^2 }A+\cot^2A+2\operatorname{cosec} A\cot A = a^2b$
⇒ $a^2b=\frac{1}{\sin^2 A}+\frac{\cos^2A}{\sin^2 A}+2\frac{1}{\sin A}\frac{\cos A}{\sin A}$
⇒ $a^2b=\frac{1+\cos^2A+2\cos A}{\sin^2 A}$
⇒ $a^2b=\frac{(1+\cos A)^2}{\sin^2A}$
⇒ $a^2b=\frac{(1+\cos A)^2}{1-\cos^2A}$ [As $\cos^2A+\sin^2A=1$]
⇒ $a^2b=\frac{(1+\cos A)^2}{(1-\cos A)(1+\cos

Correct Answer: sullen

Solution : The correct choice is the first option.

It means showing irritation or resentment by refusing to talk or cooperate. In the context of the sentence, it suggests that the child became unhappy or sulky when she didn't receive all of her parent's attention.

The original sentence is an affirmative statement followed by a question tag, which is "Have you?" To make it a negative question tag, you replace "Have you?" with "Haven't you?" This maintains the correct grammatical structure for

Correct Answer: $\frac{7(a+3b)}{6}$

Solution : Given: $\frac{3a+b}{2}-\frac{a-3b}{3}+2b$
= $\frac{9a+3b-(2a-6b)}{6}+2b$
= $\frac{7a+9b}{6}+2b$
= $\frac{7a+9b + 12b}{6}$
= $\frac{7a+21b }{6}$
= $\frac{7(a+3b) }{6}$
Hence, the correct answer is $\frac{7(a+3b) }{6}$.

Correct Answer: $46 \frac{2}{3}\%$

Solution : According to the question,
Correctly answered in first 80 questions = 0.7 × 80 = 56
Remaining questions = 140 − 80 = 60
Target correct answers = 0.6 × 140 = 84
Now,
Remaining correct answers needed = Target correct answers − Correctly
