Question

If Kapil gives an interest of Rs 54 for one year at 6 % rate per annum . What is the sum He has borrowed ?

Answer 1

Answer:

si = simple interest = ₹54

p = principle = ?

r = rate = 6%

t = time = 1 year

$si \: = \: \frac{p \: \times \: r \: \times \: t}{100} \\ \\ 54 = \frac{p \: \times \: 6 \: \times \: 1}{100} \\ \\ 54 \: \times \: 100 \: = \: p \: \times \: 6 \: \times \: 1 \\ \\ 5400\: = \: p \: \times \: 6 \: \times \: 1 \\ \\ \frac{5400}{6 \: \times \: 1} \: = \: p \\ \\ \frac{5400}{6} \: = \: p \\ \\ p \: = \: rs. \: 900$

therefore,

p = ₹900
