The driver of the taxicab was wanting in civility, so Mr. Sharma asked him for his number.
"You want my number, do you?" said the driver. "Well, work it out for yourself. If you divide my number by 2,3,4,5 or 6 you will find there is always 1 over; but if you divide it by 11 there ain't no remainder. What's more, there is no other driver with a lower number who can say the same."
What was the fellow's number? posted Aug 18, 2017

LCM of 2,3,4,5,6 is 60
So, the reqd number = 60a +1, and is divisible by 11
60a+1 = 11b
b=(60a+1)÷11
= 5a +(5a+1)÷11
5a+1 should be divisible by 11
assigning the smallest value as a=2,
b= 5*2+(5*2 +1)÷11
b=11 answer Aug 19, 2017
