Step 5: 365Â  ESQL 216 JXLV 141 JMRG 86 PEVT 21 QKBI

Directions (6-7) :

We have:

• Box R is kept third from bottom at a gap of two from box S, which is kept adjacent to box Q that means box S is kept third from the top and we have two different case for box Q, in case (1) box Q is kept immediate above box S and in case (2) box Q is kept immediate below box S.
• Box P is kept at a gap of one from box Q, which means in case (1) box P is kept immediately below box S and in case (2) box P is kept immediately above box S.

Based on the above given information we get:

From I:

We have:

• Box W is neither kept at the bottom nor adjacent to box R, which means box W is kept at the topmost position. Box V is kept at a gap of two from box P, which means in case (1) box V is kept immediate below box R and in case (2) box V is kept immediate above box R.
• Box V is kept at a gap of two from box U, which means case (1) is not valid and in case (2) box U is kept at the bottom.

Based on the above given information we get the final arrangement as follow:

Thus, box R is kept immediately above box T.

Hence, the statement I alone is sufficient.

From II:

We have:

• Box W is kept adjacent to box P, which means in case (1) box W is kept immediately below box P and in case (2) the box W is kept immediately above box P.
• Box U is kept at a gap of two from box V, which is kept adjacent to box R, that means case (1) is not valid and in case (2) box V is kept immediately above box R.

Based on the above given information we get the final arrangement as follow:

Thus, box R is kept immediate above box T.

Hence, statement II alone is sufficient.

From I:

We have:

• Riya sits second to left of Dev, who sits third to right of Gaurav and One who likes Dog is an immediate neighbor of Gaurav.
• One who likes Dog sits immediate right of Raj who likes Cat, that means one who likes Dog sits immediate left of Gaurav. One who likes Dog sits second to the right of the one who likes Parrot, that means Dev likes Parrot.
• Hari sits second to the left of the one who likes Monkey, who is an immediate neighbor of Payal, that means Hari likes Dog.

Based on the above given information we get:

Since, we donâ€™t know who likes Rat, thus result canâ€™t be determined.

Hence, the statement I is not sufficient.

From II:

We have:

• Dev likes Parrot sits second to the left of Hari, who sits second to left of Riya. Payal sits second to the left of Raj, who sits immediate left of the one who likes Dog and Raj likes Cat.
• Riya likes monkey. One who likes Monkey sits second to the right of the one who likes Dog. One who likes Horse is an immediate neighbor of Hari, that means Gaurav likes Horse.

Based on the above given information we get:

Thus, Dev sits immediate right of the one who likes Rat.

Hence, statement II is alone sufficient.

We have:

• Riya sits third to the left of Hari, who sits at end of the row.
• Ravi sits immediate left of Riya and Ravi sits second to the left of Zoya, who is facing south.

Based on the above given information we get:

From I:

We have:

• Hari faces north direction so case 2 is invalid. The immediate neighbor of Zoya sits fourth to the right of Jiya, which means Jiya must facing the south.
• The person sitting at end of the row facing in opposite direction,Â  Golu sits third from one of the ends. Here case 1 also becomes invalid.

Based on the above given information, we have the following result:

Hence, statement I is not sufficient.

From II:

We have:

• Golu sits second to the left of Hari, which means case 1 and case 2 both are not valid.

Based on the above given information, we get the following result:

Hence, statement II is not sufficient.

Hence, mstatements I and II together are not sufficient.
