# Data Interpretation - Pie Charts

*Directions to Solve*

Study the following pie-chart and the table and answer the questions based on them.

Proportion of Population of Seven Villages in 1997

Village | % Population Below Poverty Line |

X | 38 |

Y | 52 |

Z | 42 |

R | 51 |

S | 49 |

T | 46 |

V | 58 |

Population of village R = 32000 (given).

Let the population of village Y be *y*.

Then, 16 : 15 = 32000 : y y = |
15 x 32000 | = 30000. | ||

16 |

Population of village Y below poverty line = 52% of 30000 = 15600.

Let N be the total population of all the seven villages.

Then, population of village T below poverty line = 46% of (21% of N)

and Population of villages Z below the poverty line = 42% of (11% of N)

Required ratio = | 46% of (21% of N) | = | 46 x 21 | = 23/11. |

42% of (11 % of N) | 42 x 11 |

Let the population of village X be *x*.

Then, 38% of x = 12160 x = |
12160 x 100 | = 32000. |

38 |

Now, if *s* be the population of village S, then

16 : 11 = 32000 : s s = |
11 x 3200 | = 22000. | ||

16 |

Population of village Y in 1997 = 30000 (given).

Let the population of village V in 1997 be *v*.

Then, 15 : 10 = 30000 : v v = |
30000 x 10 | = 20000. |

15 |

Now, population of village V in 1998 = 20000 + (10% of 20000) = 22000.

Population of village V below poverty line in 1998 = 58% of 22000 = 12760.
