Question

In how much time will the simple interest on a certain amount of money be one tenth of the principal at 10% p.a ?​​

Answer 1

Answer:

$1\frac{1}{4}$ years

Step-by-step explanation:

Let Sum = $x$

Then,

S.I= 0.125$x$ = $\frac{1}{8} x$

R = 10%

∴ $Time = \frac{100 \times x}{x \times 8\times 10}$

            $= \frac{5}{4}$

            $= 1\frac{1}{4}$
