Answer 1

Answer:

₹ 266.25 Ans

Step-by-step explanation:

From the table : Σfiui = - 35 , Σfi = 200, h = 50

Let the assumed mean, A = 275

MEAN = A + h ×(Σfiui /Σfi)

MEAN = 275 + 50 (-35/200)

= 275 - 1750/200

= 275 - 35/4

= 275 - 8.75

= 266.25

Hence, the average expenditure per household is ₹ 266.25 .
