**Question:
**

Percentage of the different products of a village in a particular district are given below. Draw a pie-chart representing this information.

Items |
Wheat | Pulses | Jwar | Grounnuts | Vegetables | Total |

% |
100 |

**Solution:**

We know:

Central angle of a component = (component value/sum of component values

Here, the total % of items = 100

Thus, the central angle for each component can be calculated as follows:

Item | In % | Sector angle | |

Wheat | 125/3 | 41.66 | 41.66/100 |

Pulses | 125/6 | 20.83 | 20.83/100 |

Jwar | 25/2 | 12.5 | 12.5/100 |

Groundnuts | 50/3 | 16.66 | 16.66/100 |

Vegetables | 25/3 | 8.33 | 8.33/100 |

Now, the pie chat representing the given data can be constructed by following the steps below:

Step 1 : Draw circle of an appropriate radius.

Step 2 : Draw a vertical radius of the circle drawn in step 1.

Step 3 : Choose the largest central angle. Here the largest central angle is 149.97o. Draw a sector with the central angle 149.97o in such a way that one of its radii coincides with the radius drawn in step 2 and another radius is in its counter clockwise direction.

Step 4 : Construct other sectors representing other items in the clockwise sense in descending order of magnitudes of their central angles.

Step 5 : Shade the sectors with different colours and label them, as shown as in the figure below.
