TMI -- if it a multiple of 10, then it of course is even, and ends in zero.
So, assuming it is a 4-digit number then, it must look like
{13579} 7 x 0
so pick any choice from that pattern of digits
you didn't say whether digits could be repeated.
So, why not 7770
What is an even number that has a seven in the hundreds place ,has an odd number in the thousands place,and is a multiple of ten?
