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
