To do:

We have to change the given statements using expressions into statements in ordinary language.

Solutions:

(a) A notebook costs Rs. \( p \). A book costs Rs. \( 3 p \).

A book costs 3 times the cost of a notebook.
(b) Tony puts \( q \) marbles on the table. He has \( 8 q \) marbles in his box.

Tony’s box contains 8 times the number of marbles on the table.

(c) Our class has \( n \) students. The school has \( 20 n \) students.

The total number of students in the school is 20 times that of our class.
(d) Jaggu is z years old. His uncle is \( 4 z \) years old and his aunt is ( \( 4 z-3) \) years old.

Jaggu’s uncle is 4 times older than Jaggu and Jaggu’s aunt is 3 years younger than his uncle.
(e) In an arrangement of dots there are \( r \) rows. Each row contains 5 dots.

The total number of dots is 5 times the number of rows.
