Question : The total surface area of a solid hemisphere is 1039.5 cm2. The volume (in cm3) of the hemisphere is: (Take $\pi=\frac{22}{7}$)
Option 1: 2425.5
Option 2: 2530.6
Option 3: 2525.6
Option 4: 2225.5
Correct Answer: 2425.5
Solution : Let $r$ be the radius of the hemisphere. We know the total Surface Area of the solid hemisphere = $3\pi r^2$ $⇒3\pi r^2 = 1039.5$ $\Rightarrow 3\times \frac{22}{7}\times r^2 = 1039.5$ $\Rightarrow r^2 = 2.25 \times 7\times 7$ $\Rightarrow r = 10.5 \ \text{cm}$ The

Question : If $x:y::2:3$ and $2:x::4:8$, then the value of $y$ is:
Option 1: 6
Option 2: 8
Option 3: 4
Option 4: 12
Correct Answer: 6
Solution : Given: $x:y::2:3$ and $2:x::4:8$ $2:x::4:8$ ⇒ $\frac{2}{x}=\frac{4}{8}$ ⇒ $4x=16$ ⇒ $x=\frac{16}{4}=4$ Now, $x:y::2:3$ ⇒ $\frac{x}{y}=\frac{2}{3}$ ⇒ $\frac{4}{y}=\frac{2}{3}$ (Putting $x=4$) ⇒ $2y=12$ $\therefore y=6$ Hence, the correct answer is 6.
Question : What is the compound interest on a sum of INR 37,500 for $1 \frac{1}{3}$ years at a rate of 12% p.a. if the interest is compounded 8 - monthly?
Option 1: INR 6,420
Option 2: INR 6,448
Option 3: INR 6,240
Option 4: INR 6,440
Correct Answer: INR 6,240
Solution : Amount = $P(1+\frac{r}{100})^{t}$ $P$ = Principal $r$ = rate $t$ = time According to the question, $r$ = $\frac{12}{12}$ × 8 = 8% per 8-months $t$ = $\frac{16}{8}$ = 2 terms Now, ⇒ Amount $= 37500 × (1+\frac{8}{100})^{2} = 37500 × (\frac{27}{25}) × \frac{27}{25}
