B Correct answer
Explanation

The time period is 1 year and 7 months, which is 1 + 7/12 = 19/12 years. Simple interest is calculated as (Principal * Rate * Time) / 100, which is (2000 * 6 * (19/12)) / 100 = 20 * 6 * (19/12) = 120 * (19/12) = 10 * 19 = 190.

AI explanation

Using the simple interest formula SI = (P * R * T) / 100, we first convert the time of 1 year and 7 months into a decimal, which is 1 + 7/12 = 19/12 years. Substituting the values gives SI = (2000 * 6 * 19/12) / 100. This simplifies to SI = 10 * 6 * 19 / 12, resulting in a simple interest of Rs. 190.
