Q. A forester wants to plant 44 apple trees,66 banana trees and 110 mango trees in equal rows(in terms of number of trees ).Also,he wants to make distinct rows of trees(i.e,only one type of tree in one row).The number of rows(minimum) that are required are ?

Read Solution (Total 1)

In such case, we first need to find the HCF of 44, 66, 110.
44 = 2*2*11;
66 = 2*3*11;
110 = 2*5*11;
HCF = 2*11 = 22.
Then, the required numbers of rows,
= {(44/22)+(66/22)+(110/22)} = 10.
