Fiona kept the following records of her phone bills for 12 months:

50, 54, 57, 48, 71, 70

Find the mean and median of Fiona’s monthly phone bills.

**Solution:-**

First arrange the values in ascending order which is given bellow

50, 55,57,64,70,71

Mean=sum of terms /number of terms

Sum of terms=48+50+54+55+55+57+59+64+66+70+71+17=720

Number of terms=12

So mean=720/12=57

7 th term is 58
