    What number must be added to each of the numbers, 5, 9, 17, 27 to make them proportionate?

    A)  2                                            

    B)  1

    C)  3                                            

    D)  5

    Correct Answer: C

    Solution :

     Four numbers are in proportion if First \[x=\frac{1740}{29}=60\]Fourth = Second \[\Rightarrow \]Third Let 'x' be added to each of the given numbers to make the numbers proportionate. Then, \[140\times 605=11\times L.C.M.\] \[\Rightarrow \]               \[L.C.M.=\frac{140\times 605}{11}=7700\]
