Taking 1 unit length =5000 mobile users, we have got the following data:
The number of mobile users in the age group 13-20 years = 25,000.
The number of mobile users in the age group 21-40 years = 40,000.
The number of mobile users in the age group 41-50 years = 35,000
The number of mobile users in the age group 61-80 years = 10,000.
From the data, the age group 21-40 years has the maximum number of mobile phone users in a city.
