Daily expenditure (in Rs.) | 100-150 | 150-200 | 200-250 | 250-300 | 300-350 |

Number of households: | $4$ | $5$ | $12$ | $2$ | $2$ |

Answer:-

Daily expenditure | No. of households $f_{i}$ | $x_{i}$ | $f_{i}x_{i}$ |

100-150 | 4 | 125 | 500 |

150-200 | 5 | 175 | 875 |

200-250 | 12 | 225 | 2700 |

250-300 | 2 | 275 | 550 |

300-350 | 2 | 325 | 650 |

$Σf_{i}=25$ | $Σf_{i}x_{i}=5275$ |
