Question

If a 4 digit number 2X Y8 is exactly divisible by 3 , then what is least value of X+Y?

Answer 1

Answer: - The least value of X + Y = 2

Detailed solution: -

Given: -

A four-digit number is = 2 X Y 8

It is said to be exactly divisible by 3.

Then,

We need to find the least value of X + Y.

So,

$2XY8\\=2+X+Y+8\\=10+X+Y$

The least value divisible by 3 if the sum of 2 and 8 is 10 will be 12.

Then,

$12=10+X+Y\\12-10=X+Y\\2=X+Y$

Therefore,

The least value of X + Y = 2.
