Answer 2

(3)Rs 34875

Step-by-step explanation:

Let x be the c.p of LCD TV

C.P of LED TV=x

Profit on LCD TV=24 %  of x=$\frac{24}{100}x=\frac{24x}{100}$

S.P of LCD TV=C.P+Profit=$x+\frac{24x}{100}=\frac{100x+24x}{100}=\frac{124x}{100}$

S.P of LED TV=x+5580

Total S.P=$x+5580+\frac{124x}{100}$

Total C.P=x+x=2x

Net profit=20 %

S.P=$\frac{profit(in\;percentage)+100}{100}\times C.P$

Using the formula

$x+5580+\frac{124x}{100}=\frac{20+100}{100}\times 2x$

$\frac{100x+124x}{100}+5580=\frac{120}{100}\times 2x$

$\frac{224x}{100}+5580=\frac{240x}{100}$

$5580=\frac{240x}{100}-\frac{224x}{100}=\frac{240x-224x}{100}$

$5580=\frac{16x}{100}$

$x=\frac{5580\times 100}{16}=34875$

Hence, the cost price of each TV=Rs 34875
