Correct Answer: 1

Solution : Given:
$\frac{\cos65^\circ}{\sin25^\circ}+\frac{\cos55^\circ}{\sin35^\circ}-\tan50^\circ\cot50^\circ$
= $\frac{\cos65^\circ}{\sin(90^\circ-65^\circ)}+\frac{\cos55^\circ}{\sin(90^\circ-55^\circ)}-\tan50^\circ\frac{1}{\tan50^\circ}$
= $\frac{\cos65^\circ}{\cos65^\circ}+\frac{\cos55^\circ}{\cos55^\circ}-1$
= $1+1-1$
= $1$
Hence, the correct answer is 1.

Correct Answer: 1360 calories

Solution : Jogging for 5 km burns 400 calories.
⇒ 1 km of jogging burns $\frac{400}{5}=80$ calories
⇒ The total distance covered in a week = 2.5 + 4 + 2.5 + 3.5 + 0.5 + 2.5 + 1.5 = 17 km
$\therefore$ 17 km of

Correct Answer: –1

Solution : $\frac{\sin 25^{\circ}\cos 65^{\circ}+\cos 25^{\circ}\sin 65^{\circ}}{\tan ^{2}70^{\circ}-\operatorname{cosec}^{2}20^{\circ}}$
$=\frac{\sin 25^{\circ}\sin 25^{\circ}+\cos 25^{\circ}\cos 25^{\circ}}{\tan ^{2}70^{\circ}-\operatorname{cosec}^{2}20^{\circ}}$
$= \frac{\sin^2 25^{\circ}+\cos^225^{\circ}}{\tan^{2}70^{\circ}-\sec^{2}70^{\circ}}$
$= \frac{1}{-(\sec^ {2}70^{\circ}-\tan^ {2}70^{\circ})}$
$= -1$
Hence, the correct answer is –1.
