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.
