Question

In a garden, there are some rows and columes. The number of trees in a row is greater than that in each column by 10 .Find the number of trees in each row if total number of trees is 200​

Answer 1

$\huge\tt\pink{Answer}$

Let there be x rows and y columns

since, the number of trees in a row is greater than the columns by 10.

Thus,

y - x = 10 or x = y -10

$y \times x = 200 \\ y(y - 10) = 200$

$y = 10± \sqrt{ \frac{100 + 800}{2} }$

$y = \frac{10±30}{2}$

y = 20,-10

Neglect the negative value, no of rows = 20
