Find the least values of x and y for which 52x3y is divisible by 6.
PLEASE TELL THE ANSWER
Answers
To be divisible by 6 it needs to be divisible by both 2 and 3
To be divisible by 2 the last number should be even i.e. 0,2,4,6,8
To be divisible by 3 sum total should be divisible by 3
The sum total is already 10 .
Nearest number of 10 divisible by 3 is 12.
So the last number shall be 2 so it is divisible by 2 and the sum total is also 12 i.e. it is divisible by both 2 and 3 i.e. divisible by 6.
