Solution:
On purchasing a bar of chocolate, the shopkeeper gives four eclairs free
On purchasing a bar of chocolate and eight eclairs, the shopkeeper gives additional five eclairs free
This can be written as a bar of chocolate + 4 eclairs free
+ 8 eclairs + 1 eclairs free
8 eclairs get 1 eclairs free
Hence 32 eclairs will get 4 eclairs free
=> 1 a bar of chocolate is eclairs free
Hence 1 a bar of chocolate = 32 eclairs
32 is the correct answer.
