The people of Namor have a peculiar number system. They use the English alphabet for writing numbers. Any letter with one straight line such as D, B, etc. is used to represent the number 1. Any letter with two straight lines (V, T, etc.) represents the number 5; any letter with three straight lines (A, Z\ etc.) represents 10 arid finally letters with four straight lines (E\ W etc.) stand for 100. Numbers are written as a sequence of letters from left to right. If the value of a letter is less than that of the one on its right, then it is subtracted from the larger one. If the values of a letter is equal to or greater than the one on its right, nothing is done. After doing all possible subtractions, the resulting numbers are added together. For example, the sequence VANE represents the number 95 [(10-5) + (100-10)]. 16. The word WANT is equal to A. 120 B. 115 C. 125 D. 35 17. Which of the following statements is true? A. MAZE = FALL B.
