The logic is:

1st diagram: (5 × 3) + (1 × 8) = 15 + 8 = 23

2nd diagram: (3 × 1) + (8 × 3) = 3 + 24 = 27

3rd diagram: (2 × 6) + (4 × 3) = 12 + 12 = 24

Similarly,

Let the missing number in the question diagram be 'a'.

Question diagram: (1 × 4) + (5 × a) = 24

⇒ 4 + 5a = 24

⇒ 5a = 24 - 4

⇒ 5a = 20

⇒ a = 20 ÷ 5

⇒ a = 4

Hence, ‘**4**’ is the correct answer.
