Question

Gita sells two objects A and B at the same price such that she makes a profit of 20% on object A and a loss of 10% on object B. If she increases the selling price such that objects A and B are still sold at an equal price and a profit of 10% is made on object B, then the profit made on object A will be nearest to

Accepted Answer

Let us assume the initial selling prices of A and B is p.

Given, she made profit of 20% on A => 1.2 * c = p => c = 5p/6 => cost of A is $\dfrac{5}{6}p$

Given, she made a loss of 10% on B => 0.9 * c = p => c = 10p/9 => cost of B is $\dfrac{10}{9}p$

Now, she sold them at a price such that a 10% profit is made on B

=> Selling price = s = 11/10 * 10/9 p => $\dfrac{11}{9}p$

=> Profit % on A = $\dfrac{\left(\dfrac{11}{9}-\dfrac{5}{6} ight)}{\left(\dfrac{5}{6} ight)} imes 100$ = 46.66% = nearly 47%
