Question

in a farm there are 600 banana trees. the number of trees in each row is 10 less than twice the number of rows. how many trees are in each row?

Answer 1

x (2x - 10) = 600
2x² - 10x - 600 = 0
x² - 5x - 300 = 0
x = 20

Answer 2

20 trees in each row

Answer 3

Let there are x rows. Then number of trees in each row is given by (2x - 10). Hence the total number of trees is
x (2x - 10) = 600
or, 2x² - 10x - 600 = 0
or, x² - 5x - 300 = 0
It solves to x = 20. So there 20 rows and 30 trees in each row.
