Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 48.
The logic followed is:
Logic: Second number × 2 = First number
First number × 2 = Third number
First row - 80, 40, 160 →
⇒ 40 × 2 = 80
⇒ 80 × 2 = 160
Second row - 30, 15, 60 →
⇒ 15 × 2 = 30
⇒ 30 × 2 = 60
Third row - 24, 12, ? →
⇒ 12 × 2 = 24
⇒ 24 × 2 = 48
Hence, the correct answer is 48.
