Question
Select the correct answerAnu sold an article for Rs.480 at some profit. Had she sold it for Rs.400, then there would have been a loss equal to one-third of the initial profit. What was the cost price of the article?OptionsRs.450Rs.430Rs.420Rs.425
Solution
To solve this problem, we need to set up a couple of equations based on the information given.
Let's denote:
- C as the cost price of the article
- P as the initial profit when the article was sold for Rs.480
From the problem, we know that:
-
C + P = 480 (since the cost price plus the profit equals the selling price)
-
C - 400 = P/3 (since when the article was sold for Rs.400, the loss was one-third of the initial profit, which means the cost price minus Rs.400 equals one-third of the profit)
Now we can solve these equations step by step.
First, express P from the first equation:
P = 480 - C
Then substitute P in the second equation:
C - 400 = (480 - C) / 3
Multiply all terms by 3 to get rid of the fraction:
3C - 1200 = 480 - C
Add C to both sides:
4C - 1200 = 480
Add 1200 to both sides:
4C = 1680
Finally, divide both sides by 4 to solve for C:
C = 1680 / 4 = Rs.420
So, the cost price of the article was Rs.420.
