What will come in place of X?

• A. 29
• B. 24
• C. 22
• D. 26

Answer 1

The correct option is A 29



Let us find the value of 'a' and 'b' to find the value of 'X'.

23 + a + 25 = 74
a = 74 - 23 - 25
a = 26

26 + 21 + b = 69
b = 69 - 26 - 21
b = 22

X + 22 + 28 = 79
X = 79 - 28 - 22
X = 29

Thus, X = 29
