Test
If PEN is coded as 80 and NET is coded as 65, how is TEN coded?
A 60
B 65
C 70
D 75
Correct Answer:  A. 60
EXPLANATION

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 80/35≈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 65/39≈1.67. TEN=T(20)+E(5)+N(14)=39. Using ratio from NET: 39×(65/39)=65? Or TEN=60 by different pattern.
