Question : If $\cos\theta - \sin\theta =0$, then $(\sin^8\theta+\cos^8\theta)$ is:
Option 1: $\frac{1}{8}$
Option 2: $ \frac{1}{4}$
Option 3: $\frac{1}{6}$
Option 4: $\frac{1}{2}$
Correct Answer: $\frac{1}{8}$
Solution : Given: $\cos\theta - \sin\theta =0$ ⇒ $\sin\theta = \cos\theta$ $\sin\theta$'s value is only equal with $\cos\theta$ when $\theta = 45°$ ⇒ $\sin\theta = \cos\theta = \frac{1}{\sqrt2}$ $(\sin^8\theta+\cos^8\theta)$ = $(\sin^845°+\cos^845°)$ = $(\frac{1}{\sqrt2})^8+ (\frac{1}{\sqrt2})^8$ = $\frac{1}{16}+\frac{1}{16}$ = $\frac{2}{16}$ = $\frac{1}{8}$ Hence, the correct answer is $\frac{1}{8}$.

Option 4: EGHGWYM
Correct Answer: EHHHUZM
Solution : Given: BLADE is written as CKBCF, and CHALK is written as DGBKL.
Add and subtract 1 alternatively to the place value of the letters of the word BLADE to find the required code – B + 1= C; L – 1 = K; A +
