Q.3 (a) Given Mannu’s age to be x years, Can you guess what (x – 2) may show?

(Hint: Think of Mannu’s younger brother) can you guess what (x + 4) may now? What (3x + 7) may show?

(b) Given Sara’s age today to be y years. Think of her age in the future or in the past.

What will the following expression indicate?

y + 7, y – 3, y + \(4\frac{1}{2} \) , y – \(2\frac{1}{2} \) .

(c) Given n students in the class like football, what may 2n show? What may \(\frac{n}{2} \) show?

(Think of games other than football).

(b) Given Sara’s age today to be y years. Think of her age in the future or in the past.

What will the following expression indicate?

y + 7, y – 3, y + \(4\frac{1}{2} \) , y – \(2\frac{1}{2} \) .

(c) Given n students in the class like football, what may 2n show? What may \(\frac{n}{2} \) show?

(Think of games other than football).

(a) Given that Mannu’s age = x years.

\(\therefore \) (x -2) years may be the age of her younger brother or younger sister.

(x + 4) years show the age of her elder brother or elder sister.

(3x + 7) years may be the age of her father, mother or uncle.

(b) y represents the age of Sara in years.

\(\therefore \) y + 7 shows her future age.

y – 3 shows her past age.

y + \(4\frac{1}{2} \) show her future age i.e., the age after four and half years.

y – \(2\frac{1}{2} \) shows her past age i.e., the age before two and half years.

(c) Number of students who like football = n

\(\therefore \) 2n = twice the number of football players may like to play cricket.

and \(\frac{n}{2} \) = half of the number of football 2
players may like to play basket ball.
