A dealer gains a selling price of 4 watches by selling 20 watches. What is the percentage of profit?
Say each watch sells for $100.
then selling 20 watches gives a revenue of $2000, out of which $400 was profit.
So cost was $1600, profit was $400.
Profit percentage
=profit/cost
=400/1600
=0.25
=25%
A dealer gains the selling price of two watches by selling ten watches. What is his profit percentage?
25
Let's assume that the selling price of one watch is $x.
So, the dealer gains the selling price of two watches, which is 2x.
If he sells 10 watches, the total revenue he earns is 10x.
Let's assume that the cost price of one watch is y.
So, the cost price of 10 watches is 10y.
The profit made by the dealer is the difference between the revenue and the cost price, which is:
10x - 10y
We know that the dealer gains the selling price of two watches, which is 2x.
So, the profit made as a percentage of the cost price is:
(2x / 10y) * 100%
Simplifying this, we get:
(2/10) * (x/y) * 100%
= 20% * (x/y)
Therefore, the profit percentage made by the dealer is 20% times the ratio of the selling price of one watch to the cost price of one watch.
Note: We cannot determine the exact profit percentage without knowing the actual values of x and y.
Well, let's do some circus math here. If the dealer sold 20 watches and made a profit of 4 watches, we can calculate the percentage of profit like this: (4 / 20) * 100 = 20%. So, the dealer made a 20% profit. Now, that's spinning plates and juggling watches all in one!
To find the percentage of profit, we need to know the cost price and the selling price of the watches. The cost price refers to how much the dealer paid for the watches, while the selling price is the price at which the dealer sold the watches.
However, in the given question, we are only given the number of watches sold and the selling price of 4 watches. We do not have complete information to calculate the percentage of profit accurately.
To determine the profit percentage, we would need to know either the cost price of the 20 watches or the selling price of all 20 watches. Without this information, it is not possible to calculate the profit percentage accurately.
