Question

At what percent above the cost price should a dealer mark computer so that after following a discount of 5%, he is still able to make a profit of 23.5%

Answer 1

let cp be 100.
so sp after 23.5% profit will be 123.5.

but for the discount of 5% ,marked price will be
123.5 +5%of 123.5 =123.5+0.05×123.5=129.675

so, the required % will be 129.675-100/100 ×100=29.675 %

Answer 2

Answer:

29.675%

Step-by-step explanation:

Let cost price be Rs.100.

Profit% = 23.5%

SP= $100+23.5\% \times 100 = 100+\frac{23.5}{100} \times 100=123.5$

For the discount of 5% ,marked price will be$123.5 +5\% \times 123.5 =123.5+0.05\times 123.5=129.675$

The required %=$\frac{ 129.675-100}{100} \times 100=29.675\%$

Hence the cost price should a dealer mark computer 29.675% so that after following a discount of 5%, he is still able to make a profit of 23.5%
