Answer: Option D
Explanation:
93 - (27 + 3) = 63
79 - (38 + 4) = 37
Therefore, 67 - (16 + X) = 42
X = 9
Answer: Option B
Putting the position of the letters in reverse order
P = 11, S = 8, V = 5 and Y = 2.
Answer: Option A
5 x 8 x 10 = 400
and 6 x 9 x 7 = 378
Therefore 5 x 7 x ? = 315
? = 9.
Answer: Option C
(16)2 = 256
Therefore, (2)2 = 4.
From I row, 1 + (1/2) = 3/2
From II row, 2 + (2/3) = 8/3
From III row, 3 + ? = 19/5
? = (19/5) - 3
? = (4/5).
(4 x 7) % 4 = 7
and (6 x 2) % 3 = 4
Therefore, (6 x 2) % 2 = 6.
3 x 5 x 4 = 60
and 5 x 7 x 4 = 140
Therefore, 4 x 4 x ? = 96
? = (96/16) = 6.
(2)2 + (4)2 = 20
(3)2 + (9)2 = 90
Therefore, (1)2 + (5)2 = 26.
(4 x 8) + 1 = 33
(5 x 9) + 1 = 46
Similarly, (7 x 11) + 1 = 78.
(915 - 364) = 551
(789 - 543) = 246
(863 - 241) = 622.
