Give me the best solution of the question of class 10th of ncert of exercise 14.1 of statistics of question no,6 give me the easy way to solve this problem sir, The table below shows the daily expenditure on food of 25 households in a locality. Find the mean daily expenditure on food by a suitable method.
Find the midpoint of the given interval using the formula.
Midpoint (xi) = (upper limit + lower limit)/2
Let is assume the mean (A) = 225
Class size (h) = 50
Mean = x̄ = A +h∑fiui /∑fi
= 225+50(-7/25)
= 225-14
= 211
Therefore, the mean daily expenditure on food is 211
