Question

If you represent the following statement in the form of a linear equation, which of the options are correct?
If we buy 2 tickets to station A and 5 tickets to station B, the total cost is Rs. 77.

• A. 3x + 2y = 77
• B. 2x + 3y = 77
• C. 2x + 5y = 77
• D. 5x + 2y = 77

Answer 1

Answer: (C), (D)

5x + 2y = 77

Let the cost of ticket to station A be x and the cost of ticket to station B be y. Then, the statement can be represented by 2x + 5y = 77. But if we let the cost of ticket to station B be x and that to station A be y, then the statement can be represented by 5x + 2y = 77.
