Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 3 : 1.
According to the given table,
Number of maths books = 17462
Number of computer books = 14308
Number of books on circuit theory = 9948
Number of books on graph theory = 642
Required ratio = (17462 + 14308) : (9948 + 642)
⇒ 31770 : 10590 = 3 : 1
