Correct Answer: –1

Solution : Given:
$x^{2}+y^{2}+2x+1=0$
⇒ $x^{2}+2x+1+y^{2}=0$
⇒ $(x+1)^2+y^2=0$
Since the addition of the squares of the two terms is zero,
So, both the terms are individually zero.
Therefore, $(x+1)^2=0$ and $y^2=0$.
⇒ $x=-1$ and $y=0$
Now, $x^{31}+y^{35}$
= $(-1)^{31}+(0)^{35}$
= –1
Hence, the correct answer is –1.

Correct Answer: Photolysis of water

Solution : The answer is the Photolysis of water.

Oxygen is created as a consequence of photosynthesis's light-dependent processes, particularly photolysis, in which water molecules are split to liberate oxygen, electrons, and protons. The reaction involved in photosynthesis is 6CO₂+6H₂O----sunlight----> C

Correct Answer: 5 : 4

Solution : Let the salary of C be $12a$.
⇒ Tax $= 12a × \frac14 = 3a$
And, savings $= 12a × \frac13=4a$
⇒ Expenditure $= 12a - 3a - 4a=5a$
⇒ Ratio of expenditure : saving $= 5a : 4a=5 : 4$
Hence, the

Correct Answer: 15%

Solution : Principal sum, $P$ = INR 12,000
Term, $n$ = 2 years
Compound interest = INR 3870
Let $R$ be the interest rate.
When compounded annually,
Compound interest = $P(1+\frac{R}{100})^n - P$
⇒ $3870 = 12000(1+\frac{R}{100})^2 - 12000$
⇒ $3870 + 12000 = 12000(1+\frac{R}{100})^2 $
⇒

Correct Answer: 360 cm²

Solution :

In $\triangle$OAB,
Slant height, $l$ = $\sqrt {h^2 + AB^2}$
= $\sqrt {12^2 + 5^2}$
= $\sqrt{169}$
= $13$ cm
Total surface area = lateral surface area + area of the base
= $\frac{1}{2}$ × perimeter of base × slant height + area
