The continuous data are grouped in three classes as 0 - 5, 5 - 12 and 12 - 21. The frequency densities of the classes 0 - 5 and 5 - 12 are in the ratio 7:3 and the total frequency of these two classes is 150. Calculate the least possible frequency of the modal class, given that the modal class is 12 - 21.
