Correct Answer: $-\frac{27}{728}$

Solution : Given:
A = $\frac{1}{7}$ and B = $\frac{1}{8}$
The average of A, B, and C = $\frac{1}{13}$
Total of A, B, and C = $\frac{1}{13}×3=\frac{3}{13}$
C = $\frac{3}{13}-(\frac{1}{7}+\frac{1}{8})$
⇒ C = $\frac{3}{13}-\frac{15}{56}$
$\therefore$ C = $-\frac{27}{728}$
Hence, the correct answer is $-\frac{27}{728}$.

Correct Answer: $\frac{1}{1-\sin A}$

Solution : $\frac{1+\sin A}{\cos ^2 A}$
= $\frac{1+\sin A}{1-\sin^2 A}$
= $\frac{1+\sin A}{(1-\sin A)(1+\sin A)}$
= $\frac{1}{1-\sin A}$
Hence, the correct answer is $\frac{1}{1-\sin A}$.

Correct Answer: 25.2

Solution : Assume the fourth proportion be $x$
So, $\frac{1.4}{8.4}$ = $\frac{4.2}{x}$
⇒ $x$ = 8.4 × 3
⇒ $x$ = 25.2
Hence, the correct answer is 25.2.
