## How do you calculate simple interest in 6 months?

**Answer Expert Verified**

- If P be any sum and r% be it’s rate of Interest per annum for t years, then interest in t years be.
- Interest ( I ) = ( Ptr ) / 100.
- Given, Sum = Rs 6400.
- Time = 6 months = 1/2 year.
- Rate = 10% p.a.
- So, interest in 6 months.
- = (Sum * Time * Rate) / 100.
- = Rs { 6400 * ( 1 / 2 ) *10 } / 100.
