This puzzle involves eight big cats released into a national park.

This puzzle involves a number of characters, so the introductions first. The five female cheetahs are called Astronomica, Biologica, Climatologica, Demographica and Ecologica, while the three males are Foxhound, Greyhound and Husky. All eight have been released into a national park, where they sit around a circle surveying their new home.

Hi Kabir, 

Let the overs remaining be x, and runs the batter has scored at that point be y.  

15 (x - 1) + y = 100 

10 (x + 1) + y = 100 

Solving, x = 5, y = 40 

So, current score being 40 and needing 60 runs in 5 overs, he needs to score at 12 runs per over. He is making these calculations after the 15th over.

Prateek Malhotra from Delhi observes: “A deliberate short run can lead to 5 runs being awarded to the opposition, so either the batter has to be smart enough to make sure it doesn't look deliberate, or be willing to award 5 penalty runs to the opposition each time he takes a short run.”
