A) 30
B) 6
C) 10
D) 15
Correct Answer: C
Solution :
Time taken by A to make one round = \[5\div \frac{5}{2}=2\,\,hours\] Time taken by B =\[\frac{5}{3}\] hours and that by C = \[\frac{5}{2}\] hours Required time = LCM of \[\left( 2,\frac{5}{3},\frac{5}{2} \right)\] \[=\,\,\,\,\,\frac{LCM\,\,of\,\,(2,5,5)}{HCF\,\,of\,\,(1,3,2)}=\frac{10}{1}\]= 10 hoursYou need to login to perform this action.
