When a discount of $25 \%$ is given on a cruise trip,the profit is $41 \% .$ If the discount is $26 \%,$ then the profit is (in $\%$)

Two successive discounts of $a \%$ and $b \%$ on the marked price of an article are equivalent to a single discount of:

The price of a shirt after $15\%$ discount is $Rs.\,119$. What was the marked price of the shirt before the discount? (in $Rs.$)

$A$ shopkeeper gives two successive discounts of $7 \%$ each on the marked price of $Rs.\, 20,000$ of an article. The selling price of the article is (in $Rs.$):

$A$ bill which is due at the end of $4 \text{ years}$ is now worth $Rs. 575$,but if it is due in $2 \frac{1}{2} \text{ years}$,it would now be worth $Rs. 620$. The sum of the bill is (in $Rs.$)

If a shopkeeper allows a $20 \%$ discount on his advertised price and makes a profit of $25 \%$ on his outlay,what is the advertised price (in $Rs.$) on which he gains $Rs. 6000$?
