Correct Answer: 5 : 7

Solution : According to the question,
$\frac{V_1}{V_2}$ = $\frac{7}{5}$
and, $\frac{h1}{h2}$ = $\frac{5}{7}$
Now, $\frac{V_1}{V_2}$ = $\frac{πr_1^{2}h_1}{πr_2^{2}h_2}$
⇒ $\frac{7}{5}$ = $\frac{5×r_1^{2}}{7×r_2^{2}}$
⇒ 49 × $r_1^{2}$ = 25 × $r_2^{2}$
⇒ $\frac{r_1}{r_2}$ = $\frac{\sqrt{25}}{\sqrt{49}}$ = $\frac{5}{7}$
Hence, the correct answer is 5 : 7.

Correct Answer: INR 400

Solution : Given: By selling an article for INR 600, a person made a profit of 50%.
We know,
Profit percentage = $\frac{\text{Selling Price - Cost Price}}{\text{Cost Price}}\times 100$
Let the cost price of the article be $x$.
⇒ $\frac{600−x}{x}×100=50$
⇒ $60000−100x=50x$
⇒ $x=\frac{60000}{150}$
⇒ $x=400$

Correct Answer: Only I

Solution : Let the speed of the boat downstream as $d$ km/hr.
