Cumulative frequency = total number of days where the average daily temperature is less than or equal to the the value in the X axis.
For example, at cum frequency = 150, X axis value is 28. So this means 150 days have less than or equal to an average daily temperature of 28 degrees Celsius.
Use this concept, you should be able to solve the questions :)
