Question

If the principle of Rs 1,200 doubles in 6 year by simple interest ,find the rate of interest

Answer 1

Hi friend
--------------
Your answer
-------------------

Principal = Rs 1200

Time = 6 years

Amount = Rs (2×1200) = Rs 2400

Simple interest = Rs (2400 - 1200) = Rs 1200

Rate of Interest = ?

$\frac{p \times r \times t}{100} = 1200 \\ \\ \frac{1200 \times r \times 6}{100} = 1200 \\ \\ r = \frac{1200 \times 100}{1200 \times 6} \\ \\ r = \frac{100}{6} \\ r = 16.66\%$

Therefore
-----------------

Rate of interest = 16.66%
