Word Problem 11 (Gain or loss percentage)
Problem 11: The cost price of 21 articles is equal to selling price of 16 articles. Find the gain or loss percentage,
a. 33.13% gain b. 33-1/4 % loss c. 25% gain d. 25% loss
Let cost price of each one article is ‘y’ Rs.
Since cost price of 21 articles is given equal to selling price of 16 article, so
Here we can see that for one article the sale price 21y/16 is greater that its cost price ‘y’. So obviously a profit will be earned !
Now we know that profit is calculated by subtracting sale price from cost price;
So, for one article the profit will be calculated by subtracting its sale price from its cost price;
So, Profit for one article is 5y/16 Rs
Now we calculate the %age which this profit amount makes !
So the profit %age is 33-1/4 %
