Question

Anjali, Bipasha, and Chitra visited an entertainment park that has four rides. Each ride lasts one hour and can accommodate one visitor at one point. All rides begin at 9 am and must be completed by 5 pm except for Ride-3, for which the last ride has to be completed by 1 pm. Ride gates open every 30 minutes, e.g. 10 am, 10:30 am, and so on. Whenever a ride gate opens, and there is no visitor inside, the first visitor waiting in the queue buys the ticket just before taking the ride. The ticket prices are Rs. 20, Rs. 50, Rs. 30 and Rs. 40 for Rides 1 to 4, respectively. Each of the three visitors took at least one ride and did not necessarily take all rides. None of them took the same ride more than once. The movement time from one ride to another is negligible, and a visitor leaves the ride immediately after the completion of the ride. No one takes a break inside the park unless mentioned explicitly.
The following information is also known.
1. Chitra never waited in the queue and completed her visit by 11 am after spending Rs. 50 to pay for the ticket(s).
2. Anjali took Ride-1 at 11 am after waiting for 30 mins for Chitra to complete it. It was the only ride where Anjali waited.
3. Bipasha began her first of three rides at 11:30 am. All three visitors incurred the same amount of ticket expense by 12:15 pm.
4. The last ride taken by Anjali and Bipasha was the same, where Bipasha waited 30 mins for Anjali to complete her ride. Before standing in the queue for that ride, Bipasha took a 1- hour coffee break after completing her previous ride
What was the total amount spent on tickets (in Rs.) by Anjali? [This Question was asked as TITA]

• A. 150 Rs.
• B. 160 Rs.
• C. 120 Rs.
• D. 140 Rs.

Answer 1

The Correct Option is D

Anjali’s Rides: 
Anjali took Ride-1 at 11 am after waiting 30 minutes (i.e., from 10:30 am).
It was the only ride where Anjali waited, meaning she started other rides immediately when the gates opened.

Cost Details:
By 12:15 pm, Anjali and Bipasha each spent Rs. 50.
 

• Ride-1: Rs. 20
• Remaining to reach Rs. 50: Rs. 30
• Ride-3: Rs. 30

Last Ride Information:
The last ride taken by Anjali and Bipasha was the same (Ride-4).
Bipasha waited 30 minutes for Anjali to finish this ride.
Bipasha took a 1-hour coffee break before queuing for Ride-4.

Additional Ride Needed:
Total spent so far: Rs. 20 + Rs. 30 + Rs. 40 = Rs. 90
Remaining to reach Rs. 140: Rs. 50
So Anjali must have taken Ride-2 (Rs. 50).

Final Summary:
Anjali’s rides:
 

• Ride-1 (Rs. 20)
• Ride-3 (Rs. 30)
• Ride-4 (Rs. 40)
• Ride-2 (Rs. 50)

Total Cost = \( 20 + 30 + 40 + 50 = \mathbf{140} \) rupees.
