A=1, P=16, P=16, L=12, E=5 are their positions in the alphabet.
In a code, FESTIVAL is represented as 6-5-19-20-9-22-1-12. What system is used?
A Reverse alphabet position B Standard alphabet position C ASCII minus 64 D Frequency in English
F=6, E=5, S=19, T=20, I=9, V=22, A=1, L=12 are standard positions in alphabet.
QUALITY is coded as QUALITU. What is the rule?
A Last two letters are swapped B Middle letters are rearranged C No vowel change, consonants reversed D Alternate letters reversed
QUALITY: Last two letters T and Y are swapped to get QUALITU. This is a simple transposition of final two letters.
In a coding system, MOTHER is coded as PQVJGT. What is the code for FATHER?
A IDVJGT B HCVJGT C IDVJGV D JGVJGT
Each letter is shifted forward by 2 positions in the alphabet. F→H, A→C, T→V, H→J, E→G, R→T.
GARDEN is coded as 7-1-18-4-5-14. Using the same pattern, how would GOLDEN be coded?
A 7-15-12-4-5-14 B 7-14-12-4-5-14 C 6-15-12-4-5-14 D 7-15-11-4-5-14
Letters are converted to their position numbers in the alphabet. G=7, O=15, L=12, D=4, E=5, N=14.
In code PROMISE becomes RPMISE. What is the pattern?
A First two letters swap places B Alternate letters shift forward C Only consonants rearrange D Each letter moves to next position
PROMISE: P and R swap, resulting in RPMISE. Only the first two letters exchange positions.
DOCTOR is coded as GQEVQT using a +3 shift cipher. How would SYSTEM be coded?
A VBVWHI B VBVWHJ C VBUWIJ D UBUWHJ
Each letter shifts forward by 3 positions. S→V, Y→B, S→V, T→W, E→H, M→I = VBVWHI.
In a code, PENCIL becomes QFODJM. What would ORANGE become?
A PSBHGF B PRANGF C PBSHGF D PSBHDF
Each letter shifts by +1. O→P, R→S, A→B, N→O, G→H, E→F = PSBOHF (re-check: O→P, R→S, A→B, N→O, G→H, E→F).
DIGITAL is coded by alternating uppercase-lowercase starting with uppercase: DiGiTaL becomes DIGITS in pattern. What is CAPITAL coded as?
A CaPiTaL B CapItAl C CAPITAL D CaPiTaL
Alternating case pattern: 1st uppercase, 2nd lowercase, etc. C-a-P-i-T-a-L = CaPiTaL.
