Question

A pie chart representing the population of four cities is shown here. read the pie chart and find the population of the city D . a = 120° b=96° c=60° d=?

Answer 1

Given: a = 120°

b = 96°

c = 60°

Total angular measure of a circle = 360°

Thus,

a+b+c+d = 360°

120+96+60+d = 360°

d = (360 - 276)°

d = 84°

Answer 2

Step-by-step explanation:

Given:

A=120 degrees

B=96 degrees

C=60 degrees

So D,

120+96+60+x=360 degrees

=276+x=360 degrees

=x=360-276

=x=84 degrees

Given,

120 degree=100 lakh

Then,

1 degree=100/120

Then,

84 degree=100/120*84

= 70

Therefore,

The population is:70 Lakhs
