Learn Position Easily
Ø left letter – left letter = left letter
e.g. position of 8th letter to the left of13th letter from left side.
13th letter from left side – 8th letter to left = 5th letter from left side is E.
In the same way…
Ø right letter – right letter = right letter
e.g. position of 8th letter to the right of 13th letter from right side.
13th letter from right side – 8th letter to right = 5th letter from right side is V.
Calculation of Position
Ø left letter – right letter = left letter
e.g. position of 8th letter to the right of 13th letter from left side.
13th element from left + 8th element from right = 21th element from left is U.
In the same way…
Ø right letter – left letter = right letter
e.g. position of 8th letter to the left of 13th letter from right side.
13th element from right + 8th element from left = 21th element from right is F.
Calculation of Position
