Answer 1

5. Given,

By selling a table for 1990, a trader gains 10%.

To find,

The cost price of the table.

Solution,

Let us assume cost price = A

Then, Selling price = cost price + profit

So, 1990 = A + A*10/100

or, 110A = 1990*100

or, A = 1990*100/110 = 1809

Cost price of the table = 1809

6. Given,

An article was sold for 1300 with a profit of 25%.

To find,

The cost price of the article

Solution,

Let cost = A

Then,

1300 = A + A *25/100

or, 1300 = 125A/100

or, A = 130000/125

or A = 1040

The Cost price of article is 1040

7) Given,

The cost price of a coat is 2600. It was sold with a profit of 5%.

To find,

The selling price of the coat.

Solution,

Selling price = 2600 + 2600 * 25/100

Selling price = 2600 + 650 = 3250

Hence, selling price of the coat is Rs. 3250

8. Given,

An item was sold for 540 at a loss of 5%.

To find,

The Cost price of the item

Solution,

Let us assume cost price = A

then,

540 = A - A * 5/100

or, 540 = 19A/20

or, A = 540 * 20/19

or, A = 568.42

Hence cost price is 568.42

6. An article was sold for 1300 with a profit of 25%. Whát was its cost price? 7. The cost price of a coat is 2600. It was sold with a profit of 5%. Find the selling price of the coat. 8. An item was sold for *540 at a loss of 5%. What was its cost price?​
