Question

साधारण ब्याज पर धन की राशि 16 वर्ष में ही दोगुनी हो जाती है। प्रति वर्ष की दर प्रतिशत ज्ञात करें

Answer 1

Hi friends

Here is your answer
Let the Sum is x
A = 2x
SI = A - P = 2x - x
= x
T =16 years

As we know
Rate of interest = SI × 100/PT
$= \frac{x \times 100}{x \times 16} \\ \\ = 6.25\%$
Therefore Rate of interest is 6.25%

Hope it helps you
