10 boys attended a basketball camp. Their height is as follows
Min Height=130cm
Avg Height=150cm
Max Height=160cm
What is the maximum number of boys who are at least 140cms in height?

• total height of 10 boys= 10*150=1500 cms.
  total height of 8 boys = 1500-130-160=1210 cms
  avg height of 8 boys = 1210/8= 605/4 = 151.25 cms
  so these 8 boys can have height more than 140 cms also.
  so max 9 boys are atleast 140 cms in height.

• 9 boys.
  
  Out of 10 students maximum of 9 students are atleast 140cms in height.
  
  Explanation:
  
  One boy is 130cm height as given.
  One other boy is 169cm as given.
  
  As the question is about maximum, it is considered that another boy also is 160cm in height.
  
  Average height is mentioned as 150. And the Average of these 3 boys height is 130+160+160/3 = 150.
  
  So remaining 7 boys can be 150cm each.
  
  Hence maximum 9 boys can be atleast 140cms in height.
