Problema Solution
Suppose the number of people working in a certain country in a certain year age 55 or over was 30.9 million. Thirty percent of these workers were 65 or older. How many workers were age 65 or older?
Answer provided by our tutors
Number of people above a age of 55 = 30.9 million
30% of this is above a age of 65. Hence the number of people above 65
= (30/100) x 30.9 million = 0.3 x 30.9 million = 9.27 million
