The population of a town increases 10% annually. If its present population is 40,000 find its population after 3 years.
- 42,400
- 43,240
- 50,280
- 53,240
Answer: (4) 53, 240
Explanation:-
The Present population of a town = 40,000
The population of a town increases 10 % annually.
Then, population after 1 year = 40,000 + 40,000 x 10/100
= 40,000 + 4,000
= 44,000
The population after two years = 44, 000 + 44,000 x 10/100
= 44, 000 + 4,400
= 48, 400
The population after three years = 48, 400 + 48, 400 x 10/100
= 48, 400 + 4, 840
= 53, 240
Hence, the answer is (4) 53, 240.
