  • A. 4
  • B. 8
  • C. 12
  • D. 10
Correct Answer: Option B - Such as, Column 1 → 2 × 18 – (22 – 18) = 36 – 4= 32 Column 2 → 2 × 24 – (32 - 24) = 48 – 8 = 40 Same as, Column 3 → 2 × 5 – (7 – 5 ) = 10 – (7 – 5) = 10 – 2 = 8 ∴ Hence, ? = 8
B. Such as, Column 1 → 2 × 18 – (22 – 18) = 36 – 4= 32 Column 2 → 2 × 24 – (32 - 24) = 48 – 8 = 40 Same as, Column 3 → 2 × 5 – (7 – 5 ) = 10 – (7 – 5) = 10 – 2 = 8 ∴ Hence, ? = 8
