Question

The amusement park celebrates its 2 Decade anniversary next year. Shalini is now curious to know when was the amusement park formed, if this year is 2022?

Answer 1

Solution:
1 Decade = 10 years
The amusement park is celebrating its 2 Decade anniversary next year, 2023
2 Decade = 20 years
The amusement park was established 20 years before 2023.
The amusement park was established in 2023 - 20 years= 2003
So the amusement park was established in 2003.
