The cost of a notebook is twice the cost of a pen. Consider the cost of a notebook to be ₹t and that of a pen to be ₹p. Charlie wrote t = 2p, whereas Meera wrote p = 2t. Which of these two representations is correct?

Charlie’s representation t = 2p is correct. Since the cost of a notebook is twice that of a pen, the notebook price t must equal two times the pen price p. Meera’s equation is incorrect.

    1. Charlie’s equation t = 2p is the correct representation. According to the problem, the cost of one notebook is twice the cost of one pen. Representing the notebook cost as ₹t and the pen cost as ₹p gives the relation t = 2 × p. In contrast, Meera’s equation p = 2t falsely states that the pen costs twice as much as the notebook.
