Question

A farm has 15 rows of fruit trees with 7 trees in each row. The last 4 rows of trees are cherry trees. The remaining trees are orange trees. How many orange trees are on the farm?

Answer 1

Total number of orange trees = 77 trees

Explanation:

Given:

Total number of rows = 15

Total number of cherry rows = 4

Number of trees in each rows = 7

Find:

Total number of orange trees

Computation:

Total number of orange trees = [Total number of rows - Total number of cherry rows][Number of trees in each rows]

Total number of orange trees = [15 - 4]7

Total number of orange trees = [11]7

Total number of orange trees = 77 trees
