A forester wants to plant 66 apple trees 88 banana trees and 110 mango trees in equal row also he wants to make distinct rows of trees i.e only one type of tree in one row .the number of minimum rows requiredare:-

(A)2

(B)3

(C)10

(D)12

66 = 2 × 3 × 11

88 = 2 × 2 × 2 × 11

110 = 2 × 5 × 11

So, HCF of 66, 88 and 110 is 2 × 11 = 22

Thus, Number of rows of apple trees = 66/22 = 3

Number of rows of banana trees = 88/22 = 4

Number of rows of mango trees = 110/22 = 5

Hence, required number of rows = 3 + 4 + 5 = 12
