Percentage
The entire population can be divided into three non overlapping parts: owns both a car and a motorcycle, owns a car but not a motorcycle, and owns a motorcycle but not a car. If we denote these categories by A, B and C respectively, we know that A + B + C = 100%. Also, since A + B consists of all the people who own a car, we have A + B = 90%. Therefore, C must be 10%. But C is the category of people who own a motorcycle but do not own a car
