  • question_answer If \[\frac{3}{4}=\frac{x}{28}=\frac{y}{32}\], then the values of x and y respectively are

    A)  21, 24

    B)  21, 28

    C)  18, 24

    D)  21, 25

    Correct Answer: A

    Solution :

    We have, \[\frac{3}{4}=\frac{x}{28}\Rightarrow \frac{3\times 7}{4\times 7}=\frac{x}{28}\] \[\Rightarrow \frac{21}{28}=\frac{x}{28}\] \[\Rightarrow x=21\] Also, \[\frac{3}{4}=\frac{y}{32}\Rightarrow \frac{3\times 8}{4\times 8}=\frac{y}{32}\Rightarrow \frac{24}{32}=\frac{y}{32}\] \[\therefore y=24\]
