CAT 2017 – Data Interpretation

As per the question, number of dorms with repair cost as 3 crores = 3

Since Dorm 1 and 2 already have the repair cost as Rs. 3 crores.

So, out of Dorm 5 and 9, only one can have the repair cost as Rs. 3 crores

Total cost = 3+3+3/4+6+4/3 = 19

Ans : 19

4 of the 10 dorms are women’s dorms which need Rs.20 crore for repairs. As per the question, from 1 to 5 there is only one women’s dorm. This is possible with repairing costs Rs.6, Rs.6, Rs.5 and Rs.3 crore. Among the first 5, dorm 4 should be women’s dorm. Rs.6 cr dorms can only be dorm 7 and dorm 10. Rs.3 crore can be from dorm 1, 3, 5 or 9. But 1, 3 or 5 are not women’s dorm. So it has to be dorm 9. The repair cost for dorm 9 is Rs.3 crore. So, 3 crore is the right answer.

Answer: 3

4 of the 10 dorms are women’s dorms which need Rs.20 crore for repairs. Also from 1 to 5 there is only one women’s dorm. This is possible with repairing costs Rs.6, Rs.6, Rs.5 and Rs.3 crore.
