Correct Answer: Rs. 1856.40

Solution : Here p = Rs. 4000, r = 10%, t = 4 years.
We know the compound interest = $p[(1+\frac{r}{100})^t–1]$
$=4000[(1+\frac{10}{100})^4–1]$
$=4000[(\frac{11}{10})^4–1]$
$= 4000[(\frac{14641}{10000})–1]$
$= 4000[\frac{4641}{10000}]$
$=1856.4$
So, the compound interest is Rs. $1856.40$.
Hence, the correct answer is Rs. 1856.40.

Correct Answer: –20

Solution : Given: $x + y + z = 0$ and $x^2+y^2+z^2=40$
⇒ $(x+ y + z)^2= 0$
⇒ $x^2 + y^2 + z^2 + 2(xy + yz + zx) = 0$
⇒ $40 + 2(xy + yz + zx) = 0$
⇒ $2(xy + yz +

Correct Answer: 6

Solution : Let $x = \sqrt{30+\sqrt{30+\sqrt{30+...}}}$
So, ${x = }\sqrt{30+x}$
By squaring both sides, we get,
$⇒x^{2}=(\sqrt{30+x})^{2}$
$⇒x^{2}=30+x$
$⇒x^{2}–x–30=0$
$⇒x^{2}– 6x+5x–30=0$
$⇒x(x–6)+5(x–6) = 0$
$⇒(x–6)(x+5)=0$
$⇒x=6,–5$
A square root cannot be negative. Thus, $x$ cannot be –5.
So, $x = 6$
Hence, the correct answer is 6.
