| Understanding | Application |
| Tricks |
The no. of trees of state A in 2014, 2016 and 2017 = 70 + 78 + 92 = 240 |
| Now |
The number of trees of state B in 2015 and 2017 = 118 + 72 = 190 |
| Hence |
Percentage difference = 240 trees = 100% So 190 trees = 100/240 × 190 = 1900/24 = 79.16 = 79.2 So 100 - 79.2 = 20.8 |
