the value of television two years ago was 70000 it @ rate of 4 % p.a. finds its present value

Dear student,

Here we use the compound interest formula,

$$\begin{gathered} A=P{\left(1+\frac{R}{100}\right)}^n \\ A=? \\ P=70000 \\ R=4\% \\ n=2 years \\ A=70000{\left(1+\frac{4}{100}\right)}^2=70000{\left(1+0.04\right)}^2=70000\times 1.0816 \\ A=75712 \end{gathered}$$
The cost of television after two years is Rs 75,712.
