- Question
- Statements:
F ? X < A, R < X ? F
Conclusions:
I. F ? E II. R < F
Options- A. If only conclusion I follows
- B. If only conclusion I follows
- C. If either conclusion I or II follows
- D. If neither conclusion I nor II follows
- Correct Answer
- If only conclusion I follows
ExplanationSplit them as F ? X ...(i) X < A ...(ii)
R < X ...(ii) and X ? E ...(iv)
Combining (i) and (iv) we get
F ? X ? F or F ? E.
Hence I follow.
From (i) and (iii) R and F can't be compared. Hence II does not follow. - 1. Statements:

Correct Answer: If neither conclusion I nor II follows
Explanation:
V ? K > M = N > S
K > T
I. T < N is not true, II. V = S is true.
Correct Answer: If only conclusion I follows
Explanation:
Y < J = P ? R > I
I. J > I is true, II. Y < R is not true.
Correct Answer:
Explanation:
Split them as L > U ...(i)
Combining (i) and (ii),
We get L > U > Z or L > Z
Hence I follows.
Combining (ii) and (iv) we get K ? U < R or K < R Hence II follows.
Correct Answer: If only conclusion II follows
Explanation:
A ? B = C < D ? E
I. D > A is not true, II. E > C is true.
Correct Answer: If either conclusion I or II follows
Explanation:
If either conclusion I or II follows
Correct Answer: +, =, -
Explanation:
?100 + ?16
= ?225 -?1
10 + 4 = 15 - 1
? 14 = 14
Correct Answer: = ÷ - +
Explanation:
From option (c),
24 = 34 ÷ 2 - 5 + 12
? 24 = 17 - 5 + 12
? 24 = 29 - 5
? 24 = 24
Correct Answer: 16
Explanation:
32 D 4 B 7 C 2 A 6
= 32 ÷ 4 + 7 x 2 - 6 = 8 + 7 x 2 - 6
= 8 + 14 - 6 = 22 - 6 = 16
Correct Answer: 11
Explanation:
? 40 B 8 T 6 M 3 K 4 = ?
? 40 ÷ 8 - 6 + 3 x 4 = ?
? 5 - 6 + 12 = ?
? 17 - 6 = ?
? ? = 11
Correct Answer: 27
Explanation:
Here, Right number - Left number = Middle number
As, 43 - 16 = 27, 48 - 36 = 12
similarly, 56 - 29 = 27
? ? = 27
