Daily expenditure (in Rs.)	No. of households
100-150	4
150-200	5
200-250	12
250-300	2
300-350	2

• B. 201
• C. 215
• D. 209

Answer 1

The correct option is A 211

The mean daily expenditure on food can be calculated using direct method,

Daily [Expenditure]	No. of households [Frequency]	$x_i$	$f_i{x}_i$
100-150	4	125	500
150-200	5	175	875
200-250	12	225	2700
250-300	2	275	550
300-350	2	325	650
Total	25		5275

$\text{Mean daily expenditure on food}=\frac{\sum f_i{x}_i}{\sum f_i}$

$=\frac{5275}{25}$

$=211$
