Solution

The correct option is D 14
Percentage of the food sector out of the total sectors =10%
Percentage of the clothing sector out of the total sectors =40%

In a pie chart, the total angle at the centre of the circle is 360.

Central angle made by the food sector =10% of 360
=10%×360
=10100×360
=110×360
=36

Central angle made by the clothing sector =40% of 360
=40%×360
=40100×360
=25×360
=144

Ratio of central angle made by the food sector to the clothing sector
=36144
=14

Option (d.) is the correct choice.
