The table shows the percentage distribution of population across five age groups for cities A to E.

City	0-13	13-19	19-35	35-60	Above 60
A	18	12	24	30	16
B	16	18	22	29	15
C	20	20	20	25	15
D	15	18	21	26	20
E	18	15	25	24	18

If the population of city C and city D in the age group above 60 years is 24,000 each, then what is the sum of the total populations of city C and city D?

A2.4 lakh

B2.8 lakh ✓ Correct

C3.2 lakh

D4.8 lakh

Correct answer: (B) 2.8 lakh

Explanation

The sum of the total populations is 2.8 lakh, so that is the answer.

In city C the above-60 group is 15 percent and equals 24,000, so the total C is 1,60,000.

In city D the above-60 group is 20 percent and equals 24,000, so the total D is 1,20,000.

Adding these gives 1,60,000 plus 1,20,000.

That is 2,80,000.

So the sum is 2.8 lakh.
