    What is the sun of \[\frac{3}{4},\frac{7}{6}\] and \[1\frac{3}{5}\] ?

    A)  \[3\frac{1}{2}\]               

    B)         \[3\frac{31}{60}\]  

    C)  \[2\frac{13}{60}\]           

    D)         \[\frac{412}{120}\]

    Correct Answer: B

    Solution :

       To find the sum of \[\frac{3}{4}+\frac{7}{6}+1\frac{3}{5}\],find the L.C.M. of the denominators and then add them. L.C.M. of 4, 5 and 6 is 60. \[\therefore \]  \[\frac{3}{4}+\frac{7}{6}+1\frac{3}{5}=\frac{3}{4}+\frac{7}{6}+\frac{8}{5}=3\frac{31}{60}\]
