Select the combination of letters that, when placed in the blanks of the given letter series in order, will complete the series.
_ D P _ P D C _ Q D _ C P D _ D Q _ P C P _ C D
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → QCDPCDD
In a letter series with blanks, look for a block of letters that repeats; the blanks are then the letters the block needs at those places. The 24 places split into three blocks of eight; the second and third blocks together show the block Q D P C P D C D.
Block 1: _ D P _ P D C _ needs Q, C, D
Block 2: Q D _ C P D _ D needs P, C
Block 3: Q _ P C P _ C D needs D, D
The series is QDPCPDCD QDPCPDCD QDPCPDCD, and the blanks in order are QCDPCDD.
