    Find the value of y, if \[\frac{3y-1}{5}+\frac{y-1}{2}=3+\frac{1+y}{2}\]

    A)  5                                

    B)  6              

    C)  7

    D)  8

    Correct Answer: C

    Solution :

    (c) \[\frac{2\left( 3y-1 \right)+5\left( y-1 \right)}{10}=\frac{30+5\left( 1+y \right)}{10}\] \[\Rightarrow 6y-2+5y-5=30+5+5y\] \[\Rightarrow 6y=42\]             \[y=7\]
