Question

mr mehta borrowed a sum of money at 8% per annum if he paid 640 as interest after 5 years 3 months find the sum borrowed by him

Answer 1

Rate = 8%

Time = 5 year 3 month = 5.25 year
( 3 month = 3/12 year = 1/4 = 0.25 year)

SI = ₹640

Principal = ?

$SI= \frac{PTR}{100} \\ \\ \Rightarrow 640 = \frac{P \times 5.25 \times 8}{100}$

$\Rightarrow P = \frac{100 \times 640}{5.25 \times 8} \\ \\ \Rightarrow P = 1523.8$

Thus, the sum borrowed by him is ₹1523.8
