At a management school, the oldest 10 dorms, numbered 1 to 10, need to be repaired urgently. The following diagram represents the estimated repair costs (in Rs. Crores) for the 10 dorms. For any dorm, the estimated repair cost (in Rs. Crores) is an integer. Repairs with estimated cost Rs. 1 or 2 Crores are considered light repairs, repairs with estimated cost Rs. 3 or 4 are considered moderate repairs and repairs with estimated cost Rs. 5 or 6 Crores are considered extensive repairs.

1. Odd-numbered dorms do not need light repair; even-numbered dorms do not need moderate repair and dorms, whose numbers are divisible by 3, do not need extensive repair. 

2. Dorms 4 to 9 all need different repair costs, with Dorm 7 needing the maximum and Dorm 8 needing the minimum.

The total cost of repairing the odd-numbered dorms is Rs.19 crores.

The dorms that need to be repaired are 1, 3, 5, 7, and 9. The costs of repairing these dorms are Rs.3 crores, Rs.3 crores, Rs.4 crores, Rs.6 crores, and Rs.3 crores respectively.

The total cost of repairing these dorms is 3 + 3 + 4 + 6 + 3 = 19 crores.

Therefore, the answer is 19.

Here is a breakdown of the costs of repairing the odd-numbered dorms:

Dorm 1: Rs.3 crores

Dorm 3: Rs.3 crores

Dorm 5: Rs.4 crores

Dorm 7: Rs.6 crores

Dorm 9: Rs.3 crores

The total cost of repairing these dorms is 3 + 3 + 4 + 6 + 3 = 19 crores.
