      Question

      In a botanical park, 50% of the trees are neem trees. The

      number of eucalyptus trees is 35% of the neem trees, and the number of bamboo trees is 80% of the eucalyptus trees. If there are 112 bamboo trees, calculate the total number of trees in the park.
      A 800 Correct Answer Incorrect Answer
      B 720 Correct Answer Incorrect Answer
      C 620 Correct Answer Incorrect Answer
      D 700 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let total number of trees in the park be 100x

      Number of neem trees = 0.50 Γ— 100x = 50x

      Number of eucalyptus trees = 0.35 Γ— 50x = 17.5x

      Number of bamboo trees = 0.80 Γ— 17.5x = 14x

      So, 14x = 112

      x = 8

      Total number of trees in the park = 100x = 800
