If the number of people in the age group 19 to 35 years in city A is 31,680, then how many people are above 60 years of age in city A?
A21,120 ✓ Correct
B24,280
C23,680
D19,350
Correct answer: (A) 21,120
Explanation
The number above 60 years is 21,120, so that is the answer.
In city A the 19 to 35 group is 24 percent and equals 31,680.
So the total population of city A is 31,680 divided by 0.24, which is 1,32,000.
The above-60 group is 16 percent of the total.
16 percent of 1,32,000 is 21,120.
So the number above 60 years is 21,120.
