Correct Answer: 7 cm

Solution : Given,
Height = 15 cm
Curved surface area = 330 cm²
We know,
The curved surface area of the cylinder = $\pi dh$, where $d$ = diameter and $h$ is the height.
⇒ $330=\pi\times d\times 15$
⇒ $330=\frac{22}{7}\times d\times15$
⇒ $d=\frac{330\times7}{22\times15}$
⇒ $d=7$

Correct Answer: 66

Solution : Given: The average of 4 consecutive numbers is 64.5.
Let the 4 numbers be $x$, $x+1$, $x+2$ and $x+3$, respectively.
The sum of the 4 numbers $=x+x+1+x+2+x+3=4x+6$
Use the formula, $\text{Average}=\frac{\text{Sum of all values}}{\text{Total number of values}}$
According to the question,
$\frac{4x+6}{4}=64.5$
⇒ $\frac{4x+6}{4}=64.5$
⇒

Correct Answer: Rs. 30000

Solution : Amount = $P \times (1 + \frac{R}{100})^T$
where $P$ = Principal or the initial amount, $R$ = rate of interest and $T$ = time.
⇒ $15000 = 7500 \times (1 + \frac{r}{100})^2$
⇒ $2 = (1 + \frac{r}{100})^2$
⇒ $[(1 + \frac{r}{100})^2]^2=(2)^2$ [Squaring both
