    Three consecutive numbers such that thrice the first, 4 times the second and twice the third together make 188. Find the least of the consecutive numbers.

    A)  18                               

    B)  21            

    C)  19                               

    D)  20

    Correct Answer: D

    Solution :

    (d): \[3\left( a-1 \right)+4a+2\left( a+1 \right)=188\] \[\Rightarrow 9a-3+2=188\] \[\Rightarrow 9a=189\] \[\Rightarrow a=21\] \[a-1=20\] (ans).
