In each of the following word-number pairs, the number represents the sum of the alphabetical positions of the letters in the word (A = 1, B = 2 ,..., z = 26 . Four of the pairs follow this rule exactly. One does not. Identify the odd one out.
STONE: 73
GLASS: 58
BRICK: 44
WALL: 48
CEMENT: 60

Given: 

STONE: 73
GLASS: 58
BRICK: 43
WALL: 48
CEMENT: 60 ​​

Logic: Sum of place value of letters = Number

For, STONE: 73

19 + 20 + 15 + 14 + 5 = 73

73 = 73

For, GLASS : 58

7 + 12 + 1 + 19 + 19 = 58

58 = 58

For, BRICK : 44

2 + 18 + 9 + 3 + 11 = 43

43 $$\neq$$​ 44​

For, WALL - 48

23 + 1 +12 + 12 = 48

48 = 48

For, CEMENT - 60

3 + 5 + 13 + 5 + 14 + 20 = 60

60 = 60

So, option (a) is odd one out. Because BRICK = 43 $$\neq$$ 44​

Thus, correct option is (a).
