Question 8

In a certain code language, PENINSULA is written as 111. How will DICHOTOMY be written as in that language?

Accepted Answer

Assign A=1, B=2... Sum the position values of consonants and vowels separately. PENINSULA: Consonants (P+N+N+S+L) = 16+14+14+19+12 = 75. Vowels (E+I+U+A) = 5+9+21+1 = 36. Concatenate these sums: 7536. Sum of digits of 7536 = 7+5+3+6 = 21. Multiply by 5 + 6 = 111. DICHOTOMY: Consonants (D+C+H+T+M+Y) = 4+3+8+20+13+25 = 73. Vowels (I+O+O) = 9+15+15 = 39.
