When calculating the "cost per call" in such plans, it is often interpreted as the effective average cost: Total Monthly Bill / Total Number of Calls in the Month. Different call slabs have different rates, but the fixed rental also contributes to the overall cost per call when averaged across all calls.
A mobile company charges a fixed rental of Rs.350 per month. It allows 200 calls free per the number of calls exceeds 200 per month and ceeds 400 per month. A customer made 150 calls in February and 250 calls in March. By how much percent each call is cheaper in March than each call in February for that customer?
