Correct Answer: –1

Solution : Given:
$\frac{-1}{729},\frac{-1}{81},\frac{-1}{9},?$

Multiply the previous term by 9 to obtain the missing term.
$\frac{-1}{729}×9=\frac{-1}{81};\frac{-1}{81}×9=\frac{-1}{9};\frac{-1}{9}×9=-1$

So, –1 is the missing term in the given series. Hence, the second option is correct.

Correct Answer: 22.6%

Solution : Percentage increase in population in 2005 = 6%
Percentage increase in population in 2006 = 3%
Single increase percentage = $6+3+\frac{6×3}{100}=9.18$%
Percentage increase in population in 2007 = 4%
Single increase percentage of 9.18% and 4% = $9.18+4+\frac{9.18×4}{100}=13.55$%
Percentage increase in population in 2008 =

Correct Answer: 23 1/2 degree

Solution : The correct answer is 23.5 degree.

Earth' axis of rotation is inclined at 23.5 degree from its orbital plane. Although this inclination varies slightly because of the gravitational attraction of sun and moon. This is responsible for the weather phenomenons on earth and

Correct Answer: 1,10,000

Solution : $P=P{_0}​×(1+r)^t$
where: $P$ is the present population, $P{_0}$​ is the past population, $r$ is the annual growth rate (as a decimal), and $t$ is the number of years.
Given, $P{_0} = 133,100$
$r = 10\%$
We have to find the population 2 years ago ($t=−2$

Correct Answer: 84

Solution : Given: The difference between the areas of two concentric circles is 264 cm².
The area of the circle $=\pi R^2$ where $R$ is the radius.
According to the question,
$\pi R^2–\pi r^2=264$
⇒ $\frac{22}{7}\times(R^2–r^2)=264$
⇒ $(R^2–r^2)=\frac{264\times 7}{22}$
⇒ $R^2–r^2=\frac{1848}{22}=84$
Hence, the correct answer

Correct Answer: Rockets

Solution : Let's check each option –
First option: Stars→The heavenly bodies of the Universe.
Second option: Planets→The heavenly bodies of the Universe.

Correct Answer: 90 days

Solution : Given: A can do in one day three times the work done by B in one day. They together finish $\frac{2}{5}$th of the work in 9 days.
Let the efficiency of B = $a$ units,
So, the efficiency of A = 3$a$ units
Here,
