Solution : Given: 876= 12, 864= 81, 895= 22, 824=?

Here,

In 876: 8+7+6= 21, reversing the digits= 12

In 864: 8+6+4= 18, reversing the digits= 81

In 895: 8+9+5= 22, reversing the digits= 22

Similarly, In 824: 8+2+4= 14, reversing the digits=

Correct Answer: Rs. 171

Solution : Cost price = Rs. 200
Loss = 10%
Reduction = 5%
Selling price = 200×$\frac{90}{100}$×$\frac{95}{100}$ = Rs. 171
Hence, the correct answer is Rs. 171.

Correct Answer: $x^4$

Solution : Given: $x^9 \times x^5 \times x^{-4} \times x^0 \times x^{-6}$
$=x^{9+5-4+0-6}$
$=x^{4}$
Hence, the correct answer is $x^{4}$.

Correct Answer: 2

Solution : Given: $(x^2-2x+1)=0$
⇒ $x^2+1=2x$
Divide the given equation by $x$ on both sides, we get,
⇒ $x+\frac{1}{x}=2$
On squaring the above equation on both sides, we get,
⇒ $x^2+\frac{1}{x^2}+2=4$
⇒ $x^2+\frac{1}{x^2}=2$
On squaring the above equation on both sides, we get,
⇒ $(x^2+\frac{1}{x^2})^2=2^2$
⇒ $(x^4+\frac{1}{x^4})+2=4$

Correct Answer: 18

Solution : Given: $\frac{8+2 \sqrt{3}}{3 \sqrt{3}+5}=a \sqrt{3}–b$
Rationalize the given fraction,
$\frac{(8+2 \sqrt{3})\times(3\sqrt3–5)}{(3 \sqrt{3}+5)\times (3\sqrt3–5)}=\frac{24\sqrt3–40+18–10\sqrt3}{27–25}$
⇒ $\frac{14\sqrt3–22}{2}=7\sqrt3–11$
Now, compare the value with the given expression $a \sqrt{3}–b$, we get,
$7\sqrt3–11=a \sqrt{3}–b$
⇒ $a=7,b=11$
The value of $a + b=7+11=18$.
Hence, the correct answer is 18.
