Answer:

Explanation:

total marks = 65

student got marks after decrement = 54

= 11 / 65 * 100

Answer:

decrease of ≈ 16.9%

Explanation:

percentage decrease is calculated as


(decrease)/(original) × 100%

decrease = 65 - 54 = 11 , then

percentage decrease =
(11)/(65) × 100% ≈ 0.1692.. × 100% ≈ 16.9% ( nearest tenth)
