Solution(By Examveda Team)

Logic:
Reading each row of the diagram as a series of 3 digit numbers, the center 3 digit number equals either the sum of the top 2 numbers or the sum of the lower 2 numbers.

Sum of top two numbers
179 + 363 = 542

Sum of lower two numbers
275 + 26X = 542
26X = 542 - 275
26X = 267
X = 7
Missing number = 7
