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.

(b) 45000

(c) 2500

**(d) 3500**

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