Answers :
Directions (1-3) :
1) Answer: (D)
14 * 11 = 154 (Rule II)
154 – 64 =90 (Rule IV)
90/10 = 9 (Rule I)
9 + 7 = 16 (Rule III)
Resultant of the second row = 16
2) Answer: (B)
93 + 43 = 136(Rule III)
136 – 64 = 72(Rule IV)
56/8 = 7(Rule I)
7 + 11 = 18(Rule III)
Sum of the resultants of the two rows =72 + 18 = 90
3) Answer: (D)
130 – 81 = 49(Rule IV)
49 + 31 = 80(Rule III)
160 / 80 = 2(Rule V)
2 * 3 = 6(Rule II)
Resultant of the second row = 6
Directions (4-7) :
The Shop A sold on one of the days after Friday. On Wednesday, the number of Mobiles sold is 12. There are three shops sold mobiles between the shops F and D. There are two shops sold mobiles between the shop F and the shop which one sold 6 Mobiles. The sum of Mobiles sold on Wednesday and Saturday is equals to the number of Mobiles sold on Friday. The shop which sold more than 12 Mobiles (not an odd number) is immediately after the one which sold 12 Mobiles. The shop F sold Mobiles on one of the days after the shop which sold 6 Mobiles. The difference between the numbers of Mobiles sold on Monday and Friday is the multiples of 7. Shop B sold Mobiles on one of the days immediately before the shop which sold 10 Mobiles. There are two shops sold mobiles between B and G.
CASE 1
Shop B sold Mobiles on one of the days immediately before the shop which sold 10 Mobiles, so case 1 can be cancelled.

CASE 2
4) Answer: B
5) Answer: C
6) Answer: D
7) Answer: D
Directions (8-10) :
8) Answer: E
From I:
We have:
- Box U is kept third from top and is kept at a gap of two boxesfrom P that means box P is kept at bottom.
- Box R is neither kept adjacent to box P nor box U that means box R kept at top.
- Box T is kept at any place below box U but not exactly below, that means box T is kept just above box P.
Based on above given information we have:
Clearly, we don’t know position of box Q.
Thus, statement I is not sufficient.
From II:
We have:
- Only one box is kept below box T, which is kept at a gap of two from box S that means box T is kept second from bottom.
- Box R is kept adjacent to box S and is at a gap of one box from box U, that means box R is kept at top.
Based on above given information we have:
Clearly, we don’t know exact position of box Q.
Thus, statement II is not sufficient.
From I and II:
After combining above given statements we get:
Clearly, Box T is kept just below box Q.
Thus, statement I and II together are sufficient to answer the question.
Hence, option E is correct choice.
9) Answer: A
From I:
We have:
- F is the daughter of R and is sister-in-law of U. As U isan unmarried member of family, that means F must be married to the brother of U.
- K is thebrother of G, who is married to R that means F must be daughter of G.
- M is the only son of H and is nephew of U, as only two married couples are inthe family, that means H must be married to F. U is the sister of H.
Based on above given information we have:
Hence, statement I is sufficient to answer the question.
From II:
We have:
- F is the only daughter of R, who is married to H. M is the grandson of H and is son of G.
- U is sister-in-law of F and daughter-in-law of H, only two married couple are there in family and F is only daughter of R, that means G must be son of H and married to U. H is the brother of K.
Based on above given information we have:
Clearly, gender of K is not known, thus relationship can’t be determined.
Hence, statement II is not sufficient to answer the question.
So, if the data in Statement I alone is sufficient to answer the question, while the data in Statement II alone is not sufficient to answer the question.
Hence, option A is correct choice
10) Answer: E
From I:
We have:
- T sits fourth tothe left of S, who sits second to the left of Q that means T must sits at extreme left end.
- Only one person sits between V and P, who sits immediate left of S, that means we have two possible place for V, in case (1) V sits left of P, in case (2) V sits right of P.
- U neither sits at end nor immediate neighbor of P.
Based on above given information we have:
Clearly, exact position of U is not known.
Thus, we can’t determine who sits immediate left of U.
Hence, statement Iis not sufficientto answer the question.
From II:
We have:
- Q sits fourth to the right of R. Either Q or R sits at end of the row.
- Only one person sits between T and R, who sits immediate right of V that means Q sits on extreme right end. T doesn’t sit immediate neighbor of U that means T must sits at left end.
Based on above given information we have:
Thus, we can’t find who sits immediate left of U.
Hence, statement II is not sufficientto answer the question.
From I and II:
After combining above statements clearly, case (2) is not valid.
Case (2) is not valid as in statement II, V sits immediate left of R.
Clearly, S sits immediate left of U.
Hence, statement I and II together are sufficient.
So, if the data in both the Statements I and II are together are necessary to answer the question.
Hence, option E is correct choice.
