To calculate Darshan's percentage improvement in history, we need to find the difference between his scores in the mid-term and end-of-term tests and then determine what percentage this difference represents. Here's how you can do it:
1. Find the difference between the scores: Subtract the mid-term score from the end-of-term score.
End-of-term score - Mid-term score = 15 - 4 = 11
2. Determine the percentage improvement: Divide the difference (11) by the mid-term score (4) and multiply by 100 to get the percentage.
(Difference / Mid-term score) x 100 = (11 / 4) x 100 = 2.75 x 100 = 275%
Therefore, Darshan's percentage improvement in history is 275%.
