Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 77280
- The population of a town = 80,000
- Population decrease in 1st year = 8%
- Population increase in 2nd year = 5%
Applying the chain percentage method, we get
⇒ 80000 × (92/100) × (105/100)
⇒ 8 × 92 × 105 = 77280
