There are 30 mango trees, 40 guava trees and 50 apple trees. The trees are planted in such a way that each row of trees contains trees of the same variety and every row contains an equal number of trees. Find the minimum number of rows in which all the trees could be planted.

• Take the HCF of 30,40 and 50.
  it comes out to be 10.
  It means each row contains maximum 10 plants.
  So, Number of rows=3+4+5=12

• 12 rows.....if we plant 10 plants in a row means we need 3 rows for mango and 4 rows for guava and 5 rows for apple so totally 3+4+5=12.

• minimum rows would be
  3 for mango
  4 for guava
  5 for apple
  so each row would contain 10 trees
  total=12 rows of 10 trees each

• Take the HCF of the trees that comes out to be 10.
  => 30/10, 40/10, 50/10 = 3,4,5 rows for each variety.

• h.c.f is 10
  so each row contains 10 same trees hence 3+4+5=13 rows
