Question

A dealer bought some chairs for Rs. 40,000/-. If he sold them for Rs. 50,000/-, making Rs. 500/- on each chair, how many chairs did he originally buy? ​

Answer 1

Answer:

The dealer originally bought 20 chairs.

Explanation:

According to the given information,

Total cost price = Rs. 40,000/-

Selling price = Rs. 50,000/-

Profit per chair = Rs. 500/-

We know that profit is calculated as the difference between the selling price and the cost price.

Therefore, we have:

Profit per chair = Selling price per chair - Cost price per chair

500 = (50000/n) - C

Also, we know that the total cost price is the product of the cost price per chair and the number of chairs. Therefore, we have:

Total cost price = Cost price per chair x Number of chairs

40000 = C x n

We can use these two equations to solve for C and n. First, we can solve for C in terms of n by substituting the second equation into the first equation:

500 = (50000/n) - (40000/n)

500n = 50000 - 40000

n = 20

Now we can use this value of n to find the cost price per chair:

C = Total cost price / Number of chairs

C = 40000 / 20

C = 2000

Therefore, the dealer originally bought 20 chairs.
