Correct Answer: INR 1,536

Solution : Let the loan amount be P.
Then using
P = $\frac{\text{A}}{(1 +\frac{\text{r}}{100})^t}$, where A is amount due, $r$ = rate of interest, $t$ = years
⇒ P = $\frac{5808}{(1+\frac{10}{100})} + \frac{5808}{(1+\frac{10}{100})^{2}}$ 
= $\frac{5808}{\frac{11}{10}} + \frac{5808}{\frac{121}{100}}$ 
= $\frac{58080}{11} + \frac{580800}{121}$ 
= $5280 + 4800$
=

Correct Answer: 36

Solution : Given: The number of total population is 200 crore.
Country 2 = 24% of the population which is the most populated
And, Country 6 = 6% of the population which is the least populated
The difference = $200\times [\frac{24}{100}-\frac{6}{100}]$
= $200\times \frac{18}{100}=36$ crore
Hence, the

Correct Answer: $3$

Solution : $\frac{3\sin\theta+2\cos\theta}{3\sin\theta–2\cos\theta}$
Divide both sides by $\cos\theta$,
= $\frac{\frac{3\sin\theta}{\cos\theta}+2}{\frac{3\sin\theta}{\cos\theta}–2}$
= $\frac{3\tan\theta+2}{3\tan\theta–2}$
= $\frac{3×\frac{4}{3}+2}{3×\frac{4}{3}-2}$
= $\frac{6}{2}$
= 3
Hence, the correct answer is $3$.
