Explanation

Principal amount (X) = 65800

Rate of interest (R) = 14% per annum

Time (T) = 4 years

Simple interest (SI) = (X x R x T) / 100

= (65800 x 14 x 4) / 100

= 36848

Total amount (A) = Principal + Simple interest

= X + SI

= 65800 + 36848

= 102648

So, Ali will indeed get a total amount of 102648 at the end of 4 years.
