Question 465822
The problem as I understand it:
:
A five digit even number:
The product of the one's place and hundreds place is six. 
The sum is five times the tens place.
What is greatest even number?
:
Five digits, a, b, c, d, e
:
"The product of the one's place and hundreds place is six"
e * c = 6
Since the number is even, e = 2, therefore c = 3
:
"The sum is five times the tens place."
e + c = 5d
2 + 3 = 5d
5 = 5d
d = 1
:
The greatest even number: 99312
