Prev
A garden has 2000 trees. 12% of these are mango trees 18% lemon and the restare orange trees. Find the number of orange trees.
Answer:
Given details are,
Total number of trees = 2000
Number of mango trees = 12% of 2000
= (12/100) × 2000
= 240 trees
Number of lemon trees = 18% of 2000
= (18/100) × 2000
= 360 trees
Number of orange trees = 2000 – (Number of mango trees+ Number of lemon trees)
= 2000 – (240+360)
= 2000 – 600
= 1400 trees
∴ Number of orange trees are 1400 trees
