If the data in both statement I and statement II are necessary to answer the question.
Step-by-step solution
Six batsmen are doing net practice on six days of a week starting from Monday to Saturday. Only one player practises on one day.
Dhoni& practises on which day?
Statement I:& Virat practises just before Dhoni, who is not the last one to practise. Rohit& practises on the first day of the week immediatley followed by Shikhar.
Statement II:& Rohit and Virat& practise at a gap of one day such that Rohit& on Monday. Dhoni practises just before Rahul.&
Checking statement I:
But we can't determine one single day when Dhoni practises.
Dhoni& practises on which day?
Statement I:& Virat practises just before Dhoni, who is not the last one to practise. Rohit& practises on the first day of the week immediatley followed by Shikhar.
Statement II:& Rohit and Virat& practise at a gap of one day such that Rohit& on Monday. Dhoni practises just before Rahul.&
Checking statement I:
| Days | Players |
| Monday | Rohit |
| Tuesday | Shikhar |
| Wednesday | Virat/ |
| Thursday | Virat/Dhoni |
| Friday | Dhoni/ |
| Saturday |
But we can't determine one single day when Dhoni practises.
Hence data in statement I alone is not sufficient to answer the question.
Checking statement II:
But we can't determine one single day when& Dhoni& practices.
Checking statement II:
| Days | Players |
| Monday | & Rohit |
| Tuesday | |
| Wednesday | & Virat |
| Thursday | & Dhoni |
| Friday | Rahul/Dhoni |
| Saturday | Rahul |
But we can't determine one single day when& Dhoni& practices.
Hence data in statement II alone is sufficient to answer the question.
Checking statements I and II:
| Days | Players |
| Monday | & Rohit |
| Tuesday | Shikhar |
| Wednesday | & Virat |
| Thursday | & Dhoni |
| Friday | Rahul |
| Saturday | Not known |
Though we are not yet sure who practises on Saturday, we got to know that Dhoni practices on Thursday.&
Hence the data in statement I and statement II together are sufficient to answer the question.
Hence option D is correct.
Hence the data in statement I and statement II together are sufficient to answer the question.
Hence option D is correct.
