Assuming the shares of ABC at the end of Monday = 100
Therefore, XYZ shares = 50
XYZ shares decreased by 1/5 for two consecutive days (Tue and Wed) = (50 - 50*0.2) = 40 (end of day 1) ----> (40 - 40*0.2) = 32 (end of day 2 (Wednesday))
Similarly, ABC shares increase by 1/4 for two consecutive days (Tue and Wed) = 100 + 100*0.25 = 125 (end of day 1) ----> (125 + 125*0.25) = 125 * 1.25
Now, solving, ABC/XYZ = (125 * 1.25 )/ 32
This rounded off gives 4.
Answer (B)
Edit: Checked my calculation again.
The number would be closer to 5.
Answer would be (C).

Explanation:
ABC share on monday = 1000
so xyz will be = 500
now xyz share decreased by 1/5 for 2 days: 500x0.8x0.8 = 320
abc share increased by 1/4 for next 2 days: 100x1.25x1.25 = 1562.5
So Ratio: 1562.5/320 = 4.88 = 5(aprox)
IMO-C
