If A = 2, B = 4, C = 6, what is the value of D + E?
18
20
22
24
18
In this coding pattern, each alphabet letter is assigned a numerical value equal to twice its standard position in the English alphabet (A=12=2, B=22=4, C=3*2=6). Following this rule, the value for D (position 4) is 8 and the value for E (position 5) is 10, yielding a sum of 18 for D + E.

Alphabetical coding-decoding and logical series completion form foundational components of the General Intelligence and Reasoning section in RRB JE CBT-1 and other Indian competitive examinations.
Letter D corresponds to alphabetical position 4, making its coded value 8.
Letter E corresponds to alphabetical position 5, making its coded value 10.
Adding the values of D and E together results in 8 plus 10, which equals 18.
Such coding-decoding problems test the candidate's speed in mapping letters to numbers and identifying arithmetic patterns.
Options B, C, and D are incorrect arithmetic outcomes derived from miscalculating the positional values or applying incorrect multipliers.
A is correct тАФ The calculated sum of the coded values for letters D and E equals 18.
Memorizing standard and reverse alphabetical position numbers (A=1 to Z=26) is essential for quickly solving coding-decoding and analogy questions in railway recruitment tests.
