CAT 2008 — DILR Question 24
Answer the following question based on the information given below.
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 was found that the volume of data transfer in India is the same as that of Singapore. Then which of the following statements are true?
Answer & solution
- A
Total revenue is the same in both countries
- B
Total revenue in India is about 2 times that of Singapore
- C
Total revenue in India is about 4 times that of Singapore
- D
Total revenue in Singapore is about 2 times that of India
Total revenue in Singapore is about 4 times that of India
Let the total revenue for India be USD x and for Singapore be USD y.
× Total revenue = ARDT × Volume
From the diagram we can deduce the following values for the quantities.
Percentage of revenue from Data Transfer for India = 9
Percentage of revenue from Data Transfer for Singapore = 20.5
ARDT for India = USD 1
ARDT for Singapore = USD 9
It is given that the volume of data transfer in India is the same as that in Singapore
∴ y = 3.95x
∴ y is about 4 times x
Hence, option (e).
