Answer 1

$\tt{Solution \: \: (a) : }$

Cost price of a table=₹ 5600

Marked price of the table :-

= 20% above cost price

$= \frac{20}{100} \times 5600 + 5600$

$= \frac{112000}{100} +5600$

$= 1120 + 5600$

$=\bold{ ₹ \: 6720}$

Thus, the marked price was=₹6720

Therefore, the marked price of the table was=₹6720

$\tt{Solution \: \: (b) : }$

The cost price of a table=₹5600

It's marked price :-

$= 5600 + \frac{20}{100} \times 5600$

$= 5600 + \frac{20 \times 5600}{100}$

$= 5600 + \frac{112000}{100}$

$= 5600 + 1120$

$=\bold{₹ \: \: 6720}$

Thus, the marked price of the table= ₹6720

Discount applied on the marked price=10%

Selling price of the table after the discount :-

$= 6720 - 10 \: \% \: \: of \: \: 5600$

$= 6720 - \frac{10}{100} \times 5600$

$= 6720 - \frac{10 \times 5600}{100}$

$= 6720 - \frac{56000}{100}$

$= 6720 - 560$

$=\bold{₹ \: 6160}$

Thus, the amount of discount given was=₹560

Therefore, the cost of discount given on the table was= ₹560

$\tt{Solution \: \: (c) : }$

The cost price of a table =₹5600

Marked price of a table :-

$=5600 + 20 \: \% \: of \: 5600$

$= 5600 + \frac{20}{100} \times 5600$

$=5600 + \frac{20 \times 5600}{100}$

$= 5600 + 1120$

$= \bold{₹ \: \: 6720}$

Thus, the marked price of table= ₹6720

Discount applied on it =10%

The selling price of the table :-

$= 6720 - \: 10\% \: \: of \: \: 5600$

$= 6720 - \frac{10}{100} \times 5600$

$= 6720 - \frac{10 \times 5600}{100}$

$= 6720 - \frac{56000}{100}$

$= \bold{ ₹ \: 6160}$

Thus, the selling price was= ₹6160

Therefore, the selling price of the table was= ₹6160

$\tt{Solution \: \: (d) : }$

The cost price of a table =₹5600

The selling price of a table=6160

We know that :-

$\bold{profit = selling \: price - cost \: price}$

Profit earned by the carpenter:-

$= 6160 - 5600$

$= \bold{₹ \: 560}$

Which means :-

$\bold{profit \: percentage = \frac{profit \times 100}{CP} }$

Percentage of profit earned by the carpenter :-

$= \frac{560 \times 100}{5600}$

$= \frac{56000}{5600}$

$= \bold{10 \: \%}$

Thus, the profit percentage =10%

Therefore, the percentage of profit earned by the carpenter =10%
