Question

in what time does a sum of money becomes 2 times at the simple interest of 3% per annum​

Answer 1

Answer:

Therefore, in $33\frac{1}{3}years.$ a sum of money becomes 2 times.

Step-by-step explanation:

Let the principal(P) =Rs.x. Amount(A) =Rs.2x, Time = t

∴S.I.=A - P = Rs.2x−Rs.x=Rs.x, R% = 3%

We know that,

$S.I.=\frac{P.R.t}{100} \\=>x=\frac{x.3.t}{100}\\=>100=3t\\=>t=\frac{100}{3}\\ =>t=33\frac{1}{3}yr.$
