Question

If the 4-digit number 2X Y7 is exactly divisible by 3, then what is the least value of (X + Y)?

Answer 1

Answer:

Zero

A number is divisible by 3 ...the sum of the digits of the number is also divisible by 3.

Hence...

2+X+Y+7=9+(X+Y)

the sum is having numeral part and variables..

9 is divisible by 3...

So the least value of (X+Y)is "0"(Zero)

the possible values are...0,3,6,912,...
