Question

The marked price of a LCD TV is Rs. 45400. A shopkeeper allows three successive discount of $10\%,5\%$ and $2\%$ or $10\%$ and a free mobile phone. Find the cost of mobile phone being offered.

Answer 1

$45,400$

After $10\%$ discount

$\frac{90}{100}\times 45,400=40,860$

After $5\%$ discount

$\frac{95}{100}\times 40,860=38,817$

After $2\%$ discount

$\frac{98}{100}\times 38,817=38,040.66$

$10\%$ discount on this price is the cost of a mobile phone.

$\frac{90}{100}\times 45400=40860$

Cost of mobile phone$=40860-38040.66=2819.4Rs$

The price of the mobile phone is $Rs.2819.4$
