If in the English alphabet, all letters at odd numbered positions are written in serial order from left to right followed by the letters at even numbered positions written in reverse order, which letter will be sixth to the left of seventeenth letter from left ?
If all letters at odd positions are written in serial order from left to right, then this series will be :
A C E G I K M O Q S U W Y
After this even positioned letters are written in reverse, the series becomes :
A C E G I K M O Q S U W Y , Z X V T R P N L J H F D B
Now, 17th letter from left end = T
6th letter to the left of T = U
Thus, Ans - (D)
