Answer 1

Hi,
I think this diagram was correct

Answer 2

The process is described as follows and also a diagram has been attached for your convenience.

The sectors given are food, clothing,housing,comfort,education and entertainment,miscellaneous.

Each sector's contribution is added up at first= Rs. 600+220+100+50+20+10= Rs.1000.

This is the total amount spent,i.e. Rs.1000.

Now for representing it in a pie chart we need to convert each of the amount into degrees.

Using unitary method,

Total degree of the pie chart(circle)= 360°

So total degree represents the total amount

Therefore, Rs.1000 represents 360°

So, Rs.600( food) represents = (360/1000)×600 = 216°

In this way,the angle values of all the different sectors are calculated and represented on the pie chart as shown in the diagram below.
