Consider the bar chart and answer questions based on it.
The bar chart represents number of fiction and non-fiction books in four libraries L1, L2, L3 and L4.
Total number of non fiction books = 350 + 400 + 450 + 300 = 1500
Total number of fiction books = 500 + 400 + 500 + 350 = 1750
Required ratio = 1500 : 1750 = 6 : 7.
