    If \[\frac{3}{4}\] of a number is 7 more than \[\frac{1}{6}\]of the  number, then \[\frac{5}{3}\]of the number is:

    A)  15                   

    B)  18

    C)  12                   

    D)  20

    Correct Answer: D

    Solution :

    [d] Let the number be x \[\Rightarrow \,\,\,\frac{3}{4}x=\frac{1}{6}x+7\] \[\Rightarrow \,\,\,\frac{3}{4}x-\,\frac{1}{6}x=7\] \[=\frac{+9x-\,2x}{12}=7\] \[\frac{7x}{12}=7\,\,\,\therefore \,\,\,x=12\] .\[Now,\,\,\frac{5}{3}\,\,of\,\,x=\frac{5}{3}\times 12=20\]
