| 2017 | 45000 | 55000 | 35000 |
| 2018 | 55000 | 50000 | 40000 |
What was the percentage increase in the number of teak trees that were planted by these agencies in 2017 compared to the number of teak trees that were planted by these agencies in 2016?
Answer & explanation
Correct answer: option 4
Number of teak trees planted in 2017 = 35000
Number of teak trees planted in 2016 = 25000
Required percentage = \(\frac{35000-25000 }{25000}\) × 100
= \(\frac{10 }{25}\) × 100
= 40%
