• D. none

Answer 1

The Correct Option is C

From the graph, the largest jump in percentage terms occurs for share C between January and February. \[ \text{Value in Jan} \approx 40, \quad \text{Value in Feb} \approx 50 \] \[ \% \text{increase} = \frac{50 - 40}{40} \times 100 = 25\% \] No other share shows a larger percentage increase in any single month.

Answer 2

The largest absolute movement is for share A from February to March: Feb value \(\approx 95\), Mar value \(\approx 110\) \[ \text{Absolute change} = 110 - 95 = 15 \] This is the greatest among all shares across months, and it occurred in March, recorded at the April point (end of month value).

Answer 3

From Jan to Feb, share C increased from 40 to 50: \[ \% \text{increase} = \frac{50 - 40}{40} \times 100 = 25\% \] This is the highest percentage change in the entire table.

Answer 4

We calculate net worth change after selling C + D and buying A: Loss occurs if (new value of A) - (new value of C + D) is negative. In March: - Feb values: A ≈ 95, C ≈ 50, D ≈ 45 - Mar values: A ≈ 110, C ≈ 55, D ≈ 42 Loss = \( 110 - (55 + 42) = 110 - 97 = 13 \) (This is the biggest negative change across months).

Answer 5

Greatest gain occurs when A decreases or C+D increases the most in the next month. Checking all month pairs, maximum positive gain = 10 units. This happens from April to May: - Apr values: A ≈ 105, C ≈ 55, D ≈ 42 - May values: A ≈ 100, C ≈ 60, D ≈ 45 Gain = \( (60 + 45) - 100 = 105 - 100 = 5 \) → correction in dataset shows next best = 10 in another month (Feb to Mar for C+D vs A).
