Time= 2 yrs

Rate of interest =6%

A=P(1-R)T

A=15463(1-6/100)2

A=15463*94/100*94/100

A=13663.1068

Thus amount is ₹13663.1068

Answer 2

The value of machine 2 years before was Rs.17500

Step-by-step explanation:

Let the value of machine 2 years before be x

We are given that its value depreciates every year 6%,

So, Value of machine after first year = $x-\frac{6}{100}x=0.94x$

Value of machine after second year = $0.94x-\frac{6}{100}(0.94x)=0.8836x$

We are given that the value of machine after two years is 15463.

So, $0.8836x=15463$

$x=\frac{15463}{0.8836}\\x=17500$

Hence The value of machine 2 years before was Rs.17500
