    By what number must 1789 be divided to get a quotient 29 and remainder 49?

    A)  60                         

    B)         61

    C)  59                                         

    D)  52

    Correct Answer: A

    Solution :

     By Euclid's lemma, \[\therefore \], where\[=\left( \frac{144}{48}+\frac{384}{48}+\frac{240}{48} \right)=3+8+5=16\]is the divisor. \[\frac{a}{b}\]\[\frac{c}{d}=\frac{L.C.M.(a,c)}{H.C.F.(b,d)}\] \[\Rightarrow \]               \[L.C.M.\]
