    The population of a city is 155625, for every 1000 men, there are 1075 women. If 40% of men and 24% of women be literate, then what is the percentage of literate people in the city?

    A)  30%                

    B)  32%

    C)  \[32\frac{10}{15}%\]    

    D)         \[31\frac{59}{83}%\]

    Correct Answer: D

    Solution :

    [d] Ratio of men and women = 1000 : 1075 = 40 : 43 No. of men in total population \[=\frac{40}{83}\times 155625\]                                                             = 75000 No. of women in total population = 155625 ? 75000                                                             = 80625 No. of literate men = 40% of 75000 \[=\frac{40\times 75000}{100}=30000\] No. of literate women = 24% of 80625 \[=\frac{24\times 80625}{100}=19350\] \[\therefore \] Total no. of literate people = 30000 + 19350 = 49350 \[\therefore \]Required% \[=\frac{49350}{155625}\times 100%=\frac{2632}{83}%=31\frac{59}{83}%\]
