2%

Explanation:

Original mass of water in glass = 10 ounces

amount that evaporates each day = 0.01 ounce

number of days = 20 days

Total amount that evaporated = 0.01 x 20 = 0.2 ounce

percentage of water that evaporated during this period = 0.2/10 x 100

= 2%

Hence, the percentage of the original amount of water evaporated during this period is 2%
