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