In a certain code, each letter is shifted forward by a number equal to its position in the word (first letter by 1, second by 2, third by 3, and so on). How will the word BANK be written?
BANK is coded as CCQO. The first letter moves one place, the second two, the third three and the fourth four: B becomes C, A becomes C, N becomes Q and K becomes O.
- ACCQOCorrect
- BCCQP
- CCCPO
- DBCQO
Explanation
B+1=C; A+2=C; N(14)+3=17=Q; K(11)+4=15=O. So the code is CCQO. CCPO wrongly shifts N by 2 only.
