- Question
A, B, B, D, C, F, D; H, E,?,?
Options- A. E, F
- B. F, G
- C. F, I
- D. J, F
- E. J, K
- Correct Answer
- J, F
ExplanationThe given sequence is a combination of two series :I. 1st, 3rd, 5th, 7th, 9th, 11th terms i.e. A, B, C, D, E, ? II. 2nd, 4th, 6th, 8th, 10th terms i.e. B, D, F, H, ?
Clearly, I consists of consecutive letters while II consists of alternate letters. So, the missing letter in I is F, while that in II is J. So, the missing terms i.e. 10th and 11th terms are J and F respectively.

- 1. Select the correct combination of mathematical signs to replace * signs and to balance the following equation
8 * 8 * 1 * 7 = 8
Options- A. x ÷ +
- B. + ÷ x
- C. ÷ x +
- D. + x ÷ Discuss
Correct Answer: ÷ x +
Explanation:
From option (c),
8 * 8 * 1 * 7 = 8
? 8 ÷ 8 x 1 + 7 = 8
? 8 = 8- 2. Statements
P < Q = R ? S ? T
Conclusions
I. T ? Q
II. R > P
Options- A. If only Conclusions I is true
- B. if only Conclusions II is true
- C. if either Conclusions I or II is true
- D. if neither Conclusions I nor II is true Discuss
Correct Answer:
Explanation:
Statements
P < Q = R ? S ? T
Conclusions
I. T ? Q (true)
II. R > P (true)
Hence, both conclusions are definitely true.- 3. 15 ÷ 9 x 3 - 74 + 2 = 5
Options- A. + and -
- B. ÷ and x
- C. + and ÷
- D. - and ÷ Discuss
Correct Answer: + and ÷
Explanation:
If we interchanges signs '+' and '÷', then the equation changes into
15 + 9 x 3 - 74 ÷ 2 = 15 + 27 - 37 = 5- 4. If '+' means '÷', 'x' means '+', '-' means 'x' and '÷' means '-', then which of the following equation is correct?
Options- A. 36 + 6 x 3 + 2 = 20
- B. 36 + 6 - 3 x 2 = 20
- C. 36 x 6 + 3 - 2 < 20
- D. 36 x 6 + 3 x 2 > 20 Discuss
Correct Answer: 36 + 6 - 3 x 2 = 20
Explanation:
Solve all option one by one,
36 + 6 - 3 x 2 = 20
After changing the symbol as per question,
36 ÷ 6 x 3 + 2 = 20
Apply the BODMAS rule,
? 6 x 3 + 2 = 20
? 18 + 2 = 20
? 20 = 20- 5. Statements:
H * W, W @ N, N % R
Conclusions:
I. R ? W II. N ? W III. H @ R
Options- A. Only I and II are true
- B. Only II and III are true
- C. Only I and III are true
- D. All I, II and III are true Discuss
Correct Answer: All I, II and III are true
Explanation:
H ? W ..(i) W < N ...(ii) R = N ...(iii)
Combining these we get H ? W < N = R
Hence R > W and I follows
Again N > W and II follows
And, H < R III follows- 6. Insert the arithmetical operations in the following numerical figure-
4_3_4 = 48
Options- A. + +
- B. x +
- C. + -
- D. x x Discuss
Correct Answer: x x
Explanation:
4 x 3 x 4 = 48
- 7. Statements:
D * R, R % F, F S T
Conclusions:
I. F % D II. F S D III. T © R
Options- A. Only I is true
- B. Only II is true
- C. Only III is true
- D. Only either I or II is true Discuss
Correct Answer:
Explanation:
D ? N ...(i) R = F ...(ii) F > T ...(ii)
From (i) and (ii) D ? R = F or D ? F or F ? D.
Hence either I (F = D ) or II (F > D) follows
From (ii) and (iii) R = F > T or R > T or T < R.
Hence III follows.- 8. Statements:
M S T, T @ K, K © D
Conclusions:
I. D S T II. K S M
Options- A. if only conclusion I is true
- B. if only conclusion II is true
- C. if either conclusion I or conclusion II is true
- D. if neither conclusion I nor conclusion II is true Discuss
Correct Answer: if only conclusion I is true
Explanation:
M < T ... (i) T > K ...(ii) K = D ...(iii)
From (ii) and (iii) T > K = D or D < T.
Hence I follow
From (i) and (ii) K and M can't be compared
Hence II does not follow- 9. Statements:
N < O ? R > T; R < A; B ? T
Conclusions:
I. N < A II. B < A
Options- A. if only conclusion I is true
- B. if only conclusion II is true
- C. if either conclusion I or II is true
- D. if neither conclusion I nor II is true Discuss
Correct Answer: if only conclusion II is true
Explanation:
N < O ? R > T; R < A; B ? T
Check for I:
N < O ? R > T
? No definite relation can be found between N and A.
Check for II:- 10. Which one of the four interchange in signs or numbers would make the given equation correct?
6 x 4 + 2 = 16
Options- A. + and x, and 4
- B. + and x, 2 and 4
- C. + and x, 4 and 6
- D. None of these Discuss
Correct Answer: + and x, 4 and 6
Explanation:
Apply all option one by one.
? 6 x 4 + 2 = 16 ? 4 + 6 x 2 = 16 ? 4 + 12 = 16
