Answer 1

Answer:

The rate of interest applied on sum of Rs 1 is 10.8%

Step-by-step explanation:

Given as :

The interest for 1 month = I = 0.9 paisa

i.e I = Rs 0.009

The time period = t = 1 month = $\dfrac{1}{12}$ year

The principal amount = p = Rs 1

Let The rate of interest = r %

According to question

Applying Simple Interest method

∵ Simple Interest = $\dfrac{principal\times rate\times time}{100}$

Or, I = $\dfrac{p\times r\times t}{100}$

Or, Rs 0.009 = $\dfrac{Rs 1\times r\times \frac{1}{12}}{100}$

Or, 0.009 = $\dfrac{r}{1200}$

∴  r = 1200 × 0.009

i.e r = 10.8

So, The rate of interest applied = r = 10.8%

Hence, The rate of interest applied on sum of Rs 1 is 10.8%  Answer
