Question

Sanjay bought 5 notebooks and 2 pens for Rs. 120. He told to guess the cost of each

notebook and pen to his friends Mohan and Anil. Sanjay has given the clue that both

the costs are integers and divisible by 5 such that the cost of a notebook is greater

than that of a pen.

Now, Mohan and Anil tried to guess.

Mohan said that price of each notebook could be Rs. 18. Then five notebooks would cost Rs.90,

the two pens would cost Rs.30 and each pen could be for Rs. 15.

Anil felt that Rs. 18 for one notebook was too little. It should be at least Rs. 20. Then the price of

each pen would also be Rs.10.

I. Write a linear equation in two variables for this situation

II. Draw the graph for this situation.

III. Check whether the answers of Mohan and Anil are correct.

IV. Find the cost of a notebook and a pen.

V. If Sanjay purchased 8 notebooks and 4 pens, how much money he has to pay to the

shopkeeper?

(a) Rs. 150 (b) Rs. 200 (c) Rs. 250 (d) Rs. 300
