Solution

We can form the frequency table as

Interval
Class interval(x)
Frequency(f)
x.f

0-100 50 12 600

100-200 150 28-12 = 16 2400

200-300 250 34-28 = 6 1500

300-400 350 41-34 = 7 2450

400-500 450 50-41 = 9 4050

So the average daily income-

$= \frac{(Sum of x . f)}{(Sum of frequency)}$
$= \frac{(11000)}{50}$
$= 220$
