# Change the following statements using expressions into statements in ordinary language.

(For example, Given Salim scores $ r $ runs in a cricket match, Nalin scores $ (r+15) $ runs. In ordinary language - Nalin scores 15 runs more than Salim.)

**(a)** A notebook costs Rs. $ p $. A book costs Rs. $ 3 p $.

**(b)** Tony puts $ q $ marbles on the table. He has $ 8 q $ marbles in his box.

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

**(d)** Jaggu is z years old. His uncle is $ 4 z $ years old and his aunt is ( $ 4 z-3) $ years old.

**(e)** In an arrangement of dots there are $ r $ rows. Each row contains 5 dots.

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.
