Show answer & explanation
Correct answer: D
Given: damaged Kannada books = 92.
From the table, damaged Kannada books are 2% of all Kannada books.
Total Kannada books = 92 × 100 / 2 = 4600.
From the pie-chart, Kannada = 23% of the library and English = 20% of the library.
Method 1 (direct ratio): English books = 4600 × (20 / 23) = 4000.
Method 2 (two-step): Total library = 4600 / 0.23 = 20000; English = 0.20 × 20000 = 4000.
Answer: Total English books = 4000.
