What number should replace the question mark?

The correct answer is Option (3) → 4

 

THE LOGIC FOLLOWED HERE IS

SUM OF OUTER NUMBER × 2 = INNER NUMBER

IN FIG A

(7 + 3 + 5 ) × 2

= 15 × 2

= 30

IN FIG B

(14 + 10 + 12 ) × 2

= 36 × 2

= 72

IN FIG C

(13 + 9 + 1 ) × 2

= 23 × 2

= 46

SIMILARLY

IN FIG D

(8 + X + 6 ) × 2 = 36

14 + X = 18

X = 18 - 14

X =4
