# The daily income of a sample of 50 employees are tabulated as follows

Income (in Rs.) 1-200 201-400 401-600 601-800

Number of employees 14 15 14 7

Find the mean daily income of employees

**Solution:**

Given, the data represents the daily income of a sample of 50 employees.

We have to find the mean daily income of employees.

Income (in Rs.) | Number of employees (f) | Midpoint x | f × x |

1-200 | 14 | 100.5 | 1407 |

201-400 | 15 | 300.5 | 4507.5 |

401-600 | 14 | 500.5 | 7007 |

601-800 | 7 | 700.5 | 4903.5 |

Total | ∑f = 50 | ∑fx = 17825 |

By direct method,

Mean = ∑fx / ∑f

From the table,

Mean = 17825/50

= 356.5

Therefore, the mean is 356.5
