Ticket for an adult is Rs 1600 and a child is Rs 600. One child goes free with two adults. If a group has 17 adults and 7 children, what is the discount the group gets?

Let's calculate the total cost without any scheme or offer:
Cost of 17 adults=17×1600=Rs 27200
Cost of 7 children=7×600=Rs 4200
Total original cost=27200+4200=Rs 31400
According to the offer, 1 child goes free with every 2 adults.
The group has 17 adults. The maximum number of pairs of adults is:

⌊
2
17
​
⌋=8 pairs
Since there are only 7 children in the group and we have the capacity to accommodate up to 8 free children, all 7 children will get their tickets for free.

Total discount received (value of free tickets)=7×600=Rs 4200
Now, we calculate the discount percentage:

Rounding off gives approximately 13.37%.
