18) A
Let the sample size be 100
Between 75 and 85 households own a dishwasher
Between 35 and 40 households own a tumble dryer
Less than 5 households own nothing.
Maximum value = 85 + 40 – 100 = 135 – 100 = 35%
Minimum value = 75 + 35 – 100 = 110 – 100 = 10%
Hence the answer is A (10% – 35%)
Crack BMAT 
A- between 10% and 30%. Your answer has 35%

Hi,
Thank you for the comment!
Actually I made a mistake in my workings
Mistake: 85 + 40 – 100 = 35%
Correct working: 85 + 45 – 100 = 25%
So the correct answer is A (10% – 30%)
Thank you for bring this to my attention! I have edited the workings now.
