Hemant ranks tenth in a class. How many students are there in the clas...
Statement I: His friend got 58th rank which is the last.
Statement II: Hemant's rank from the last is 49th.
To find out the number of students in the class, we need to know the position of Hemant among all the students. Let's analyze each statement:
Statement I: His friend got 58th rank which is the last.
This statement tells us that Hemant's friend secured the last position in the class, which means there are at least 58 students in the class. However, it doesn't give us any information about Hemant's rank or the number of students before him. Therefore, statement I alone is not sufficient to answer the question.
Statement II: Hemant's rank from the last is 49th.
This statement tells us that Hemant is the 49th student from the end of the class. However, it doesn't provide any information about the total number of students or Hemant's position from the beginning. Therefore, statement II alone is not sufficient to answer the question.
Combining both statements:
From statement I, we know that there are at least 58 students in the class. From statement II, we know that Hemant is the 49th student from the end. Since we are given that Hemant ranks tenth in the class, we can subtract 10 from the total number of students from the end to find Hemant's position from the beginning.
Let's assume the total number of students in the class is "x." From the end, Hemant's position is x - 49 + 1 = x - 48. From the beginning, Hemant's position is 10. Therefore, we can write the equation:
x - 48 = 10
Solving this equation, we find that x = 58.
Thus, combining both statements gives us the answer to the question. Therefore, the data either in statement I or II alone is sufficient to answer the question.
Hence, the correct answer is option C.
