# For the following distribution:

Class 0-5 5-10 10-15 15-20 20-25

Frequency 10 15 12 20 9

the sum of lower limits of the median class and modal class is

a. 15

b. 25

c. 30

d. 35

**Solution:**

Class | Frequency | Cumulative Frequency |

0-5 | 10 | 10 |

5-10 | 15 | 25 |

10-15 | 12 | 37 |

15-20 | 20 | 57 |

20-25 | 9 | 66 |

We know that

N/2 = 66/2 = 33 that lies in the interval 10-15

10 is the lower limit of the median class

20 is the highest frequency that lies between the interval 15-20

So the lower limit of modal class is 15

Required sum = 10 + 15 = 25

Therefore, the sum of lower limits of the median class and modal class is 25.
