Digits are coded as letters: 1=P, 2=Q, 3=R, 4=S, 5=T, 6=U, 7=V, 8=W, 9=X, 0=Y. Rule: if a number both begins and ends with an odd digit, code its first and last digits as Z instead. What is the code for 5837?

Question

Accepted Answer

ZWRZ. 5837 begins with 5 (odd) and ends with 7 (odd), so the rule applies: first and last become Z. The middle 8→W and 3→R stay, giving ZWRZ.
