The following frequency table shows the demand for a sweet and the number of customers. Find the mode of demand of sweet.

Given the distribution table, notice that maximum number of customers has demand for 250-500 grams. (Since, 60 is the maximum number of customers)

So, modal class = 250-500

Mode is given by

Where L = lower class limit of the modal class

h = class interval of the modal class

f₁ = frequency of the modal class

f₀ = frequency of the class preceding the modal class

f₂ = frequency of the class succeeding the modal class

Here, Modal class = 250-500

L = 250

h = 250

f₁ = 60

f₀ = 10

f₂ = 25

Putting these values in the formula,

⇒

⇒ Mode = 250 + 147.06

⇒ Mode = 397.06

Thus, mode of demand of sweet is 397.06 grams.
