Question

the sum which will earn a simple interest of rupees 126 in 2 year at 14 per annum is what

Answer 1

450.....................

Answer 2

S.I = ₹ 126
Rate of interest = 14 % p.a
Time = 2years
Let Principal (sum) = ₹ P

$S.I = \frac{P \times R \times T}{100} \\ \\ 126 = \frac{P \times 14 \times 2}{100} \\ \\ 126 = \frac{7 \times \: P }{25} \\ \\ 126 \times \frac{25}{7} = P \\ \\ 450 = P$

Principal (sum) = ₹ 450
