Answer 2

Answer: The cost of mobile phone is being offered at Rs. 2819.34.

Step-by-step explanation:

Since we have given that

Marked price of LCD TV = Rs. 45400

Successive discounts = 10%, 5%, 2%

So, the price after discounts becomes

$45400(1-0.10)(1-0.05)(1-0.02)\\\\=45400(0.9)(0.95)(0.98)\\\\=38040.66$

Or discount of 10%.

Price after discount of 10% becomes,

$45400(1-0.10)\\\\=45400\times 0.9\\\\=40860$

According to question,

$38040.66=40860-\text{Cost of mobile phone}\\\\\text{Cost of mobile phone}=40860-38040.66=2819.34$

Hence, the cost of mobile phone is being offered at Rs. 2819.34.
