B | 52 |

C | 38 |

D | 58 |

E | 46 |

F | 49 |

G | 51 |

3.1) In 1996, the population of villages A, as well as B, is increased by 10% from the year 1995. If the population of village A in 1995 was 5000 and the percentage of population below poverty line in 1996 remains same as in 1995. Find approximately the population of village B below the poverty line in 1996.

(a) 4000

(b) 45000

(c) 2500

**(d) 3500**

Solution: Population of Village B in 1995 = 5000 * (16/13) = 6150.

Population of village B in 1996 = 6150 * (110/100) = 6750

Population below poverty line = 52% of 6750 = 3500(aprox)

3.2) If in 1997 the population of village D is increased by 10% and the population of Village G is reduced by 5% from 1995 and the population of Village G in 1995 was 9000. What is the total population of villages D and G in 1997?
