Step-by-step explanation:
In less than cumulative frequency C.F is calculated by adding the class frequency and frequencies of all lower classes. For example C.F of “less than 11.5” is calculated by adding 0 with 6. Similarly C.F of “less than 17.5” is calculated by adding 6 with 23 (6 + 23 = 29) and so on.
