a) 2 years 1 months

b) 2 years 2 months

c) 2 years 3 months

d) 2 years 4 months

correct answer is: c) 2 years 3 months

**Explanation**

Here,

Principal (p) = Rs 10000

Rate = 8 %

S.I. = Rs 1800

Let, Time = ‘t’

We know,

S.I. =\frac{p\times r\times t}{100}

Or, t =\frac{S.I.\times100}{p\times r}

So, put the value, we get:

t =\frac{1800\times100}{10000\times8}

\rightarrow t =2.25 years

\therefore Time = 2.25 years or 2 years 3 months.**Ans:** In 2 years 3 months the simple interest on Rs 10000 at 8% rate of interest will become Rs 1800.

**An alternative phrasing for this particular query is:****1. Calculate the time needed for the simple interest on Rs 10000 at an 8% interest rate to reach Rs 1800.****2. Find out how many years it takes for the simple interest on Rs 10000 at 8% interest to become Rs 1800.****3. Determine the duration required for the simple interest on Rs 10000 to accumulate to Rs 1800 at an 8% interest rate.****4. In how many years will the simple interest on Rs 10000 at an 8% interest rate amount to Rs 1800?****5. Calculate the time it takes for the simple interest on Rs 10000 at an 8% interest rate to reach Rs 1800.**
