Correct Answer: if either conclusion I or II is true
Explanation:
B = N ...(i) N ? T ...(ii) T > K ...(iii)
From (i) and (ii) B = N ? T or T ? B,
Hence I either (T = B) or II (T < B) follows
Correct Answer: if neither conclusion I nor II is true
Explanation:
R < J ...(i) J > F ...(ii) F ? H ...(iii)
From (ii) and (iii) H and J can't be compared.
Hence I does not follow
From (i) and (ii) R and F can't be compared.
Hence II does not follow
Correct Answer: if only conclusion II is true
Explanation:
J > D ...(i) D = N ...(ii) N ? F ...(iii)
From (ii) and (iii) D = N ? F or F ? D ...(iv)
Hence II follows.
From (i) and (iv) R and (iv) J and F can't be compared.
Hence I does not follow.
Correct Answer: if only conclusion I is true
Explanation:
B > T ...(i) T < H ...(ii) H = M ...(iii)
From (ii) and (iii) T < H = M or M > I
Hence I follow
From (i) and (ii) B and H can't be compared. Hence II does not follow
Correct Answer:
Explanation:
W ? V ..(i) V = Z ...(ii) Z ? D ...(iii)
From (ii) and (iii) V = Z ? D or D ? V
Hence I follows.
From (i) and (ii) W ? V = Z or W ? Z
Hence II follows.
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
Correct Answer: + ÷ - =
Explanation:
Given equation ? 15 * 24 * 3 * 6 * 17
From option (a), substitute the signs
15 + 24 ÷ 3 - 6 = 17
? 15 + 24/3 - 6 = 17
? 15 + 8 - 6 = 17
? 23 - 6 = 17
? 17 = 17
Correct Answer: 9
Explanation:
(2)3 ÷ 4 = 2, (4)4 ÷ 8 = 32
Therefore, (6)2 ÷ 4 = 9
Correct Answer: 95
Explanation:
Here sign '&' does not convey any meaning and sign '%' signifies '+'
26 + 7 = 33, 46 + 8 = 54
Therefore, 6 + 89 = 95
Correct Answer: 6
Explanation:
879 ? (7 + 9) - 8 = 8
625 ? (2 + 5) - 6 = 1
and 586 ? (8 + 6) - 5 = 9
Similarly, 785 ? (8 + 5) - 7 = 6
