There are 80 families in a small extension area. 20 per cent of these families own a car each. 50 per cent of the remaining families own a motor cycle each. How many families in that extension do not own any vehicle?
Correct Answer: 32
Explanation:
Given in the question,
20% of 80 = 20 * 80 / 100 = 16
Remaining 50%
= (80 – 16) × 50 / 100 = 32
No. of families not owning any vehicle
= 80 – (32 + 16) = 80 – 48 = 32
