Answer 2

Answer:

yes.. size of new class remains the same

Step-by-step explanation:

initial upper and lower limit= 20-30

initial class size= 30-20=10

                   

adding 5 to both will give

(20+5)-(30+5)

=25-35

new upper and lower limit is 25-35

new class size= 35-25

                          =10

therefore size of new class is same
