Q.109Medium
If PEN is coded as 80 and NET is coded as 65, how is TEN coded?
Answer: A
P=16, E=5, N=14: 16+5+14=35×2=70? Rechecking: If each letter = position value, PEN=16+5+14=35. If coded as 80, factor is 3580≈2.29. Using A=1...Z=26: P(16)+E(5)+N(14)=35. NET=N(14)+E(5)+T(20)=39. If NET=65, then 3965≈1.67. TEN=T(20)+E(5)+N(14)=39. Using ratio from NET: 39×(3965)=65? Or TEN=60 by different pattern.
