Explanation:
Total number of Biscuits = 5
Total number of Candies = 3
So Total number of Savouries = 12 – 5 – 3 = 4
From point iii) and iv) it is clear that D, E, F and K are 4 savouries and are kept in shelves numbered 13,14, 15 and 16 as there is no empty shelf between items of the same type.
From point II), V and VII) I, J and L are of the same type L being in the least numbered shelf among 3.
As from point VI,) C is candy so I, J and L must be Biscuits as there are only 3 candies.
From point V) H is not Biscuits so it must be a candy thus A and B must be Biscuits.
Now Item can be placed as given below.
Case 1) when all biscuits are placed after candies.
