Class 9 maths ganita manjari part 2 chapter 13 question answer
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.
