The investigation agency has arrested the mastermind and nine other people A, B, C, D, E, F, F, H and I in this matter. Interrogating them, the following facts have been obtained regarding their operation. Initially, the mastermind obtains the correct answer key from one or two people who already posses the same. These people are called his/her "sources". If the person has two sources, then he/she compares the answer keys obtained from both sources. If the key to a question from both sources is identical, it is copied, otherwise it is left blank. If the person has only one source, he/she copies the sources answer into his/her copy. Finally, each person compulsorily replaces one of the answer(not a blank one) with a wrong answer in his/her answer key.The paper contained 200 questions; so the investigative agency out the possibility of two or more of than introducing wrong answers to the same question. The investigative agency has a copy of the correct answer key and has tabulated the following data. These data represent question numbers.
How many people (excluding the mastermind) needed to make answer keys before C could make his answer key? -

Answer the questions on the basis of the information given below:The seven basic symbols in a certain numeral system and their respective values are as follows:I = 1, V = 5, X = 10, L = 50, C = 100, D = 500 and M = 1000In general, the symbols in the numeral system are read from left to right, starting with the symbol representing the largest value; the same symbol cannot occur contiguously more than three times; the value of the numeral is the sum of the values of the symbols. For example, XXVII = 10 + 10 + 5 + 1 + 1 = 27. An exception to the left to right reading occurs when a symbol is followed immediately by a symbol of greater value; then, the smaller value is subtracted from the larger. For example, XLVI = (50 - 10) + 5 + 1 = 46.The value of the numeral MDCCLXXXVII is:
