In the orange garden there are 150 orange trees. The number of treesin each row is 5 more than that in each column. Find the number of treesin each row and column. |

Answer» The total no. of trees are 150. Let no. of trees in each column be tno. of trees in each row = t + 5Total no. of trees = no. of trees in each row X no. of trees in each column 150 = t ( t+ 5 )150 = t² + 5tt² + 5t - 150 = 0t² + 15t - 10t - 150 = 0t(t + 15) -10(t + 15) = 0(t - 10)(t + 15) = 0t = 10 or -15But t cannot be negative as it is no. of trees. So, t = 10 Therefore, no. of trees in each row is 10 + 5 = 15and in each column is 10. |
