If the number of school going children in a town is 64000 and it is increasing annually by 10%, then what will be the number of school going children in the town at the end of 3 years?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 85184.
Let's calculate the number of school-going children year by year:
Year 1:
⇒ Increase = 10% of 64000 = 6400
⇒ Total children at the end of Year 1 = 64000 + 6400 = 70400
Year 2:
⇒ Increase = 10% of 70400 = 7040
⇒ Total children at the end of Year 2 = 70400 + 7040 = 77440
Year 3:
⇒ Increase = 10% of 77440 = 7744
⇒ Total children at the end of Year 3 = 77440 + 7744 = 85184
So, at the end of 3 years, there will be 85,184 school-going children in the town.
