The number of English books is 25, the number of Math books is 75 and the number of Science books is 50. Determine the number of books in each stack such that each stack has equal number of all the subjects.

Answer 1

NO OF STACKS OF MATH BOOK = 75/ 25 = 3

NO OF STACKS OF SCIENCE BOOK = 50 /25 = 2
