Option 4 : 150
Logic: Product of digit of 3rd column ∼ Product of digit of 1st column = 2nd column
In each row, second column element is the difference of the product of the digits of first column elements and the product of digits of third column elements.
First row,
⇒ (4 × 8 × 4) ∼ (6 × 7 × 6) = 128 ∼ 252 = 124
Second row,
⇒ (5 × 7 × 6) ∼ (2 × 5 × 6) = 210 ∼ 60 = 150 = ?
Similarly,
⇒ (3 × 6 × 1) ∼ (5 × 2 × 9) = 18 ∼ 90 = 72
Hence, "150" is the missing number.
