    If 70% of the students in a school are boys and the number of girls is 420, then the number of boys is:

    A) 890                              

    B) 980

    C) 1080                            

    D) 1400

    Correct Answer: B

    Solution :

    % of boys = 70% \[\therefore \] % of girls = (100 - 70)% - 30% Now 30% of total students - 420 \[\Rightarrow \] total students =\[\frac{420\times 100}{30}=1400\] Number of boys = 1400 ? 420 = 980
