A man borrowed \(Rs. \ 30000\) from Punjab National Bank to buy a tractor. Find the amount he would pay after \(2\frac {1}{2}\) years at \(17\%\) per annum.
Answer
Principal \((P)= Rs.\ 30000\) Time \((T)= 2\frac{1}{2} \) years \( = \frac{5}{2} \) years Rate of interest \((R)=17\% \ p.a\) Therefore, Simple Interest \((S.I.) = \frac{P×R×T}{100}\) \(SI = \frac{30000×17×5}{100×2}\) \(SI =Rs. \ 12750\) Total Amount \( = P+S.I.\) \(= Rs.\ 30000 + Rs.\ 12750\) \(= Rs.\ 42750\)
