Which one will replace the question mark ?
Answer: Option C
Explanation:
(5 x 6 x 4)/10 = 12
and (6 x 7 x 5)/10 = 21
Therefore (4 x 8 x 10)/10 = 32.
13 + 15 = 28
36 + 54 = 90
Therefore, 45 + 63 = 108.
Answer: Option D
(3 x 4 - 8) = 4
(2 x 5 - 4) = 6
(4 x 5 - 9) = 11.
(3 x 3) + (5 x 6) = 39
and (4 x 4) + (5 x 7) = 51
Therefore, (3 x 4) + (5 x 5) = 37.
