    Direction: The given pictograph represents the number of visitors at a zoo on a certain day.
              Time Number of visitors
    10 a. m - 12 noon
    12 noon - 2 p. m.
    2 p. m. - 4p.m.
    4 p.m. - 6 p.m.
    6 p.m. - 8 p.m.
    Each represents 40 visitors.
    What fraction of visitors entered the zoo between 10 a.m. and 2 p.m. that day?

    A)  \[\frac{26}{29}\]                               

    B)  \[\frac{13}{64}\]       

    C)  \[\frac{13}{32}\]                   

    D)    \[\frac{26}{32}\]

    Correct Answer: C

    Solution :

    No. of visitors between 10 a.m. and 2 p.m. \[=\left( 2\frac{1}{2}+4 \right)\times 40=6\frac{1}{2}\times 40\] \[=\frac{13}{2}\times 40=260\] Total no. of visitors = 640 \[\therefore \] The required fraction \[=\frac{260}{640}=\frac{13}{32}\]
