Question

The cost of a T.V. set was quoted Rs. 17000 at the beginning of 1999. In the beginning of 2000 the price was hiked by 5%. Because of decrease in demand the cost was reduced by 4% in the beginning of 2001. What was the cost of the T.V. set in 2001?

Answer 1

Given, 

Cost of T.V at beginning og 1999 = Rs.17000 

Hiked in price in 2000 = 5% 

Depreciation in 2001 = 4% 

So, 

Price of T.V in 2001 \(= 17000({1}+\frac{5}{100})({1}-\frac{5}{10})\)

\(= 17000\times\frac{21}{20}\times\frac{24}{25}\) = Rs 17136
