Add the alphabetic numerical value of each letter in the group and then sum up the unit and tens which is equal to four everywhere, i.e., CWE = 3 + 23 + 5 = 31 which is equal to 3 + 1= 4, FQH = 6 + 17 + 8 = 31 (3 + 1) = 4 and so on
Answer: B Explanation: E is fifth from beginning of the
alphabet and V is fifth from the end.
Similarly J is tenth from the beginning and Q is 10th from the end and the same rule is followed in the other pairs of the series.
Answer: B Explanation: The first letter of every group is in
alphabetical order, i.e., KLMNO. Same
is the case with II and III letters of the group. Such as PQRST and ABCDE
Answer: A Explanation: Every next term in the series starts with a gap of one letter along with some change in the sequence of letters such as, NMO, is for MNO, RQS, is for QRS and so on.
Answer: C Explanation: Divide each member of series in this
way
B D F H and so on—one gap in
ascending order.
Y U Q M and so on—three gap
in descending order
WX Y Z and so on—no gap in
ascending order
Answer: D Explanation: Last letter in every group is falling down, i.e., SRQPO. The middle one is increasing, i.e., ABCDE and the first letter has two pairs, BB and DD.
