Which one will replace the question mark ?
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).
