In an amusement park, all rides are equally priced, and the entry ticket for the park costs an additional ₹180. Rohan had 15 rides and paid a total of ₹1,380 for his visit to the park. How much (in ₹) in all would Rohan have to pay for his visit to the amusement park if he had opted for 20 rides?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1780.
Let the cost of one ride be x.
Cost for Rohan when hr opted for 15 rides = 15x + 180
⇒ 1380 = 15x + 180
⇒ 15x = 1200
⇒ x = 80
Cost for Rohan when he opted for 20 rides = 180 + 20x
⇒ 180 + 20(80)
⇒ 180 + 1600 = 1780
