Answer 2

The new selling price of a set so as to gain 15% is Rs.15870.

Step-by-step explanation:

Given : A television manufacturer earns 20% profit by selling each T.V. set o Rs. 14400. If the production cost is increased by 15%.

To find : What should be the new selling price of a set so as to gain 15%?

Solution :

The selling price is SP=Rs.14400

The profit percentage is P%=20%

The cost price is given by,

$CP=\frac{100}{100+P\%}\times SP$

$CP=\frac{100}{100+20}\times 14400$

$CP=\frac{100}{120}\times 14400$

$CP=12000$

New cost price is given by,

$CP_n=115\%\times 12000$

$CP_n=0.115\times 12000$

$CP_n=13800$

New selling price is given by,

$SP=\frac{100+P\%}{100}\times CP$

$SP=\frac{100+15}{100}\times 13800$

$SP=115\times 138$

$SP=15870$

Therefore, the new selling price of a set so as to gain 15% is Rs.15870.
