Solution
Case 1: Taking 2 piles of Coins
- Pile 1 = P1
- Pile 2 = P2
P1 = HTTTT P2 = HHHHT
We have make both pile with equal no. of heads
Now determining the number of Heads in both the Piles
- P1 = 1 Head
- P2 = 4 Heads
P1 = HTTTT P2 = HHHHT
We have make both pile with equal no. of heads
After Flipping Pile 1
Number of Heads now in Pile 1,
- P1 = 4 Head
Number of Heads in Pile 2,
- P2 = 4 Heads
P1 = THHHH
P2 = HHHHT
After Flipping Pile 1
Conclusion:
Number of Heads now in Pile 1,
- P1 = 4 Head
Number of Heads in Pile 2,
- P2 = 4 Heads
Number of Heads in Pile 1 is equal to no. of heads in Pile 2
P1 = THHHH P2 = HHHHT
P1 = P2 = 4 Heads
