Three sets of English, Mathematics and Science contain 336, 240 and 96 books respectively.  They have to be arranged in such a manner that they are arranged subjective and their heights will be same.  Find out the number of heaps?

14

Heights of one heap = HCF of 336, 240 and 96

Heights of one heap = 48 Books

Total number of heaps = \(\frac{total\;books}{Height\;of\;one\;book}\)

                                 = \(\frac{336}{48}\) + \(\frac{240}{48}\) + \(\frac{96}{48}\) = 7 + 5 + 2 =14
