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.
The time taken by the boat to cover $x$ km in downstream = $\frac{x}{d}$ hours
Upstream = $\frac{x}{8}$ hours
According to the question,
$\frac{x}{8} = \frac{x}{d} + 3$
Now check the statements:
I. If

Correct Answer: 21.43%

Solution : $\frac{2}{5}$ × marked price = $\frac{4}{7}$ × cost price
Marked price = $\frac{10}{7}$ × cost price
Discount = 15% of marked price
= $\frac{15}{100}×\frac{10}{7}$ × cost price
Selling price = marked price – discount
= $(1-\frac{15}{100})×\frac{10}{7}$ × cost price
= $\frac{85}{100}×\frac{10}{7}$ × cost price
=

Correct Answer: 2555

Solution : $12.50\ ÷ \ 0.005 + 25\ ÷\ 0.5 + 5 = x$
$⇒x=\frac{12.50}{0.005}+\frac{25}{0.5}+ 5$
$⇒x=\frac{1250×1000}{5×100}+\frac{250}{5}+ 5$
$⇒x=2500+50+5$
$\therefore x=2555$
Hence, the correct answer is 2555.
