Current Plan Review Call Tariff: Rs 299 is paid as a tariff to get free call minutes Bill tells you the duration of all calls=351 minutes(335 minutes local + 11 minutes night call and 5 minutes STD) Charges(without tariff) for this plan is 30paise/min for local & night calls and 50paise/min for STD calls So by his usage of 346 minutes for local & night calls is should pay= Rs 104 but he is paying Rs.299 So he is paying a lot more than the actual charge Net Tariff: Currently he is being charged Rs 236 per 1gb data usage so he will be charged Rs 500 for his data usage which fits good with his current plan SMS tariff: He pays a tariff of Rs.50 in which he gets 288 free local messages i.e. nearly 17paise/sms His on peak time of sending sms is in evening so for that particular time he can be charged at 10p/sms and for rest of the time 17p/sms Thus his tariff can be Rs.35/month for free local SMS.

Prediction Gender-Male The call duration were less and usually females are prone to talk more compared to male. In fact, women talk almost three times as much as men, with the average woman chalking up 20,000 words in a day - 13,000 more than the average man. Approximate Age The duration of the calls is very less and thus he uses only the phone for business purposes People contacted in day is far less than a person of much younger age will do Kind of phone- Smartphone,3G enabled Huge data transfer and usage compared to a normal mobile phone Any other information- Occupation can be a businessman or an executive Data pattern- the kb/s is not used enough in any day as compared to a student. Thus we can predict the person only uses the data pack for not so heavy uses such as downloading but for basic necessities like checking s, social networking or business sites etc. Source - times-men-says-study.html
