Step-by-step explanation:

Price of 8 Mathematics books: Rs.1200

Price of 1 Mathematics book: Rs.1200/8 = Rs.150

Price of 5 English books: Rs.525

Price of 1 English book: Rs.525/5 = 105

So,

The Ratio of the price of a Mathematics book to the price of an English book,

Price of Mathematics book : Price of English book

or, 150 : 105

or, 150/105

or, 30/21
