Correct Answer: 30

Solution : The LCM of 2, 5, and 7 is 70.
Taking the 4-digit number which is divisible by 70 and lies between 4800 and 4900.
So, only one number exists(i.e. 70 × 69 = 4830). By equating both the numbers,
⇒ 48ab = 69 × 70

Correct Answer: $\frac{8}{17}$

Solution : Given, $\operatorname{cosec} \theta=\frac{17}{15}$
⇒ $\sin \theta =\frac{1}{\operatorname{cosec} \theta}= \frac{15}{17}$
Now, $\cos \theta = \sqrt{1-\sin^2 \theta}$
⇒ $\cos \theta = \sqrt{1-(\frac{15}{17})^2}$
⇒ $\cos \theta = \sqrt{\frac{64}{289}}$
⇒ $\cos \theta = \frac{8}{17}$
Hence, the correct answer is $\frac{8}{17}$.
