प्रश्न
If a note book costs Rs p and a pencil costs Rs 3, then the total cost (in Rs) of two note books and one pencil.
उत्तर
Given, Cost of one notebook = Rs. p
Cost of 2 notebooks = 2 × p = Rs. 2p
Similarly, cost of one pencil = Rs. 3
Now, Total cost = Cost of 2 notebooks + Cost of one pencil = Rs. (2p + 3)
Hence, the required expression is 2p + 3.
