    Question

    Each of the questions given below has one question and two statements marked I and II.   You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer.

    What is Joy’s position in boys when counting from

    bottom? I. There are 80 students in the class and Joy is ranked fifteenth from the top, and there are 6 girls ahead of him. II. The ratio of number of girls to boys is 1:3.
    A If the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question. Correct Answer Incorrect Answer
    B If the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question. Correct Answer Incorrect Answer
    C If the data either in statement I alone or in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
    D If the data even in both the statement I and II together are not sufficient to answer the question Correct Answer Incorrect Answer
    E If the data in both statement I and II together are needed to answer the question Correct Answer Incorrect Answer

    Solution

    From both I & II, We know that the total number of students = 80 Number of girls = 80 X ¼ = 20 Number of boys = 80 X ¾ = 60 We know that 6 girls are ahead of him which means out of total 14 students ahead of Joy, 6 are girls and 14-6 =8 are boys. Thus, 8 boys are ahead Joy + 1 Joy = 9 Total boys = 60 60 – 9 = 51 = Number of boys behind Joy. Thus, Joy is 52nd from the bottom.
