Meena starts her own coaching institute with 25 students who are studying from class VI to X. Their names are according to the English alphabetical series except for the letter 'X'. The students in each class are in a consecutive pattern. For example: if there are 2 students in class VI then there must be 3 students in class VII and 4 students in class VIII and so on. Each class from VI to X has different timings- 7 am, 8 am, 9.30 am, 10.30 am, 11 am respectively. At 12 pm Meena goes home from coaching. No student of different classes studies in the same time.
