It was eeeaaasy!

That was fun. The whole 1 second of it.
If you think it's easy, don't try these ones. Go to the harder section or try some of my math teasers.
[The age of a man is the same as his wife's age with the digits reversed.]
x = 10a + b
y = 10c + d
10a + b = 10d + c
[The sum of their ages is 99]
10a + b + 10c + d = 99
[Combine]
10d + c + 10c + d = 99
11d + 11c = 99
a = 5
b = 4
c = 4
d = 5
[The Man is 9 years older then the wife]
x = 10a + b
x = 54
husband = x
husband = 54
y = 10c + y
y = 45
wife = y
wife = 45
Therefore the husband is 54 and his wife is 45.

One of my teasers was rejected because it was too hard.
Storm, can you PM it to me?

Too EZ!!!!!!!!!!
OKOK.
I'll make harder ones.

I liked it. I got it on the first try. Yeah me! I'm a blonde at heart so I'm proud of myself!
WOW! I actually got this one and I don't get too many very often!
simple! but i liked it! i could just tell when i read it that the ages were 45 and 54
The first clue about the digits reversed is pointless since you're told that the difference between their ages is nine. It's a pointless teaser as well. Anyone using algebra to solve this should rethink:
Wife = (99 - 9) / 2 = 45
Husband = (99 + 9) / 2 = 54
Why do they even accept teasers like this?
Wife = (99 - 9) / 2 = 45
Husband = (99 + 9) / 2 = 54
Why do they even accept teasers like this?
SUPER EASY I like ones harder!
aznboi: another thing they teach you in 2nd grade is how to spell
