There are 6 volumes of books on a track kept in order (such as, vol. 1, vol. 2 and so on). Aftersome readers used them, their order got disturbed. The changes showed as follows:
Vol. 5 was directly to the right of vol. 2
Vol. 4 has vol. 6 to its and both were not at Vol. 3 splace.
Vol. 1 has Vol. 3 on right and Vol. 5 on left.
An even numbered volume is at vol. 5's place.
Find the order in which the books are kept now. from the 4 given alternatives:

There are five tracks T1 T2 T3 T4 T5
Chines ---Indian (Chinese is left of Indian)
The arrangement in this case could be :
Nepalese Iraqi Englishman Chinese Indian
So Iraqui will be on track 2.

There are five tracks T1 T2 T3 T4 T5
Chines ---Indian (Chinese is let o Indian)
The arrangement with the given condition is not possible as it contradicts the given conditions.

There are five tracks T1 T2 T3 T4 T5
Chines ---Indian (Chinese is let o Indian)
Chinese Indian and the Iraqi Nepalese Iraqi/Indian Englishmen.
Hence the Indian and the Iraqi should be in track 2 and track 4 in any order.

Given takes are A, B, C, D, E (here we will assume the condition to complete the work at the earliest)
From the 1^stcondition- Task A ? from 11 am to 9 am to 11 am,
From the 2^nd condition B ? From 11 am to 12 noon (Since it has started after completion of A)
From the 3^rd condition C ? From 12 noon to 1 pm
Task D's one hour work will be done along with B.
D's second hour work will be done along with C.
Hence to commence E, D must complete 3 hrs.
Hence timing of task D ? from 11 am to 2 pm and
After this the remaining task E ? From 2 pm to 3 pm

From the above solution E start from 2 pm.

Vicky > Priya
Priya > Ankit
One of them is true- Raman is highest or Tony is least or Sunil got highest and Deepak got least.
Now or each and every question we have different case-
Since Sunil got the sixth and Ankit got the fifth rank, hence we can conclude that Raman must have got the highest and Tony must have got the least rank. And the order of ranks of Vicky, Priya and Ankit must be Vicky > Priya > Ankit. Vicky must have got the second or third rank and accordingly Priya must have got the third or ourth rank. Deepak mlust have got any rank among two, three and four.

Vicky > Priya
Priya > Ankit
One of them is true- Raman is highest or Tony is least or Sunil got highest and Deepak got least.
Now or each and every question we have different case-
If Raman Sunil got the highest, then Tony will get least and be ranked 7th.
Now since Priya and Ankit are always ranked numerically highest than Vicky.
Hence, Vicky can never be ranked lower than 4th.

Vicky > Priya
Priya > Ankit
One of them is true- Raman is highest or Tony is least or Sunil got highest and Deepak got least.
Now or each and every question we have different case-
Given that Ankit is ranked 1st. But is not possible as he always scores less than Vicky and Priya. Hence this case is possible and data is inconsistent.

Vicky > Priya
Priya > Ankit
One of them is true- Raman is highest or Tony is least or Sunil got highest and Deepak got least.
Now or each and every question we have different case-
If Sunil gets the second rank, then Raman gets the first rank and Tony gets the last rank. In that case Vicky's rank can be 3 or 4, and Priya's rank can be 4 or 5 and Ankit's rank can be 5 or 6 then Deepak's rank can be 3, 4, or 5.

Vicky > Priya
Priya > Ankit
One of them is true- Raman is highest or Tony is least or Sunil got highest and Deepak got least.
Now or each and every question we have different case-
If Vicky is ranked 5^th , then Priya is ranked 6^th and Ankitis ranked 7^th. Then only possibility is Sunil is ranked 1^st
