Question

a nursery has 12% of mango trees 18% lemon trees and rest are orange trees if there are 1400 orange trees find the total number of trees in the nursery

Answer 1

let there are x trees in total
percent of mango trees = 12%
percent of lemon trees = 18%
total percent of mango and lemon trees = 12 + 18 = 30%
therefore percent of orange trees = 100 - 30 = 70%
number of orange trees = 1400
according to question 70% of x = 1400
◆ 70/100 × x = 1400
◆ 70x = 1400 × 100
◆ x = 1400 × 100/70
◆ x = 20 × 100
◆ x = 2000
