I am a 3 digits number less than 200. the tenths place is 2x more than the ones place. the number in the ones place is 2. what number am i?

Well lets break this up first.
Clue 1: is i am a 3 digit number less than 200, only number possible there is 1.
Clue 2: is the tens is 2x ones' place. so look at clue 3.
clue 3: The ones place is 2.
So then the tens is 2 times 2 which is 4.
So the number would be 142.
