    A person distributes his pens among four friends A. B. C. D in the ratio \[\frac{1}{3}:\frac{1}{4}:\frac{1}{5}:\frac{1}{6},\]What is the minimum number of pens that the person should have?

    A)  57                  

    B)  65

    C)  75              

    D)       45

    Correct Answer: A

    Solution :

     \[A:B:C=\frac{1}{3}:\frac{1}{4}:\frac{1}{5}:\frac{1}{6}\] \[=\frac{1}{3}\times 60:\frac{1}{4}\times 60:\frac{1}{5}\times 60:\frac{1}{6}\times 60\] [LCM of\[3.4.5\,\,\,\And \,\,6=60\]] \[=20:15:12:10\] \[\therefore \] Minimum number of pens \[=20+15+12+10=57\]
