The cumulative frequency corresponding to 40 - 50 is 35.
Step-by-step explanation:
Cumulative frequency is written as C.F.
Cumulative frequency is adding current frequency to the previous frequency.
Starting frequency is same.
Class interval: 0 - 10 10 - 20 20 - 30 30 - 40 40 - 50
Frequency : 5 15 10 2 3
C. F : 5 20 30 32 35
