Answer:
Absolute change = 3%
Relative change = 100%
Step-by-step explanation:
Current percentage = 3%
Upcoming percentage = 6%
Absolute change :
Relative change :
Absolute change = (upcoming percentage - current year percentage)
Absolute change = 6% - 3% = 3%
Relative change :
[(upcoming percentage - current year percentage) / current year percentage] * 100%
[(6% - 3%) / 3%] * 100%
(3% / 3%) * 100%
1 * 100%
= 100%

What does x= ? It doesn’t say.
Let x = number of students in each of the remaining rows
266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13
