Question

To dispose of the old stocks, a person sold a tea- set for rupees 3420,which was 43% below the cost price. In order to make a profit of 10% the seller should have sold the set for rupees ------ more.

Answer 1

The seller should have sold the set for Rs. 3180 more in order to make a profit of 10%

Explanation

Suppose, the cost price of the tea-set is  $x$ rupees.

Now, 43% below the cost price means  $(x- 0.43x)$ rupees, which is given as Rs. 3420.

So, the equation will be.....

$x-0.43x=3420\\ \\ 0.57x=3420\\ \\ x=\frac{3420}{0.57}=6000$

Thus, the cost price of the set is Rs. 6000.

If the percentage of profit is 10% , then the amount of profit $= (6000*0.10) = 600$ rupees, that means the selling price will be: (6000+600)rupees = 6600 rupees.

So, in order to make a profit of 10% , the seller should have sold the set for $(6600-3420) rupees = 3180$ rupees more.
