Telecom operators get revenue from transfer of data and voice. Average revenue received from transfer of each unit of data is known as ARDT. In the diagram below, the revenue received from data transfer as percentage of total revenue received and the ARDT in US Dollars (USD) are given for various countries.
It is expected that by 2010, revenue from data transfer as a percentage of total revenue will triple for India and
double for Sweden. Assume that in 2010, the total revenue in India is twice that of Sweden and that the volume of data transfer is same in both the countries. What is the percentage increase of ARDT in India if there is no change in ARDT in Sweden?
