Answer: 39.29%
Step-by-step explanation:
For us to calculate the percentage change, we have to deduct the trading for VEF in January from the trading for VEF in February and then divide by VEF trading in January. This will be:
= (1950 - 1400)/1950
= 550/1400
= 0.3929
= 39.29%
The percentage change in January is 39.29%.
