Answer 1

Hello

Your question seems to be incorrect. so lets assume it's asking that in how much time will a sum of money amounts to double of itself at 13℅ p. a of simple intrest.

Now,

If p= x Than, A= 2x

SI= 2x-x=x

SI=

$\frac{p \times r \times t}{100}$

$x = \frac{x \times 13 \times t}{100}$

$t = \frac{100}{13} = 7.692 \: years$
