Explanation:

For "How many people drink tea in the morning?"

Step1: Identify tea drinkers

People who drink tea include those who drink tea only and those who drink both tea and coffee.

Step2: Calculate total tea drinkers

Tea only is 20, both is 72. So total tea drinkers = 20 + 72 = 92.

Step1: Identify coffee drinkers

People who drink coffee include those who drink coffee only and those who drink both tea and coffee.

Step2: Calculate total coffee drinkers

Coffee only is 40, both is 72. So total coffee drinkers = 40 + 72 = 112.

Step1: Calculate total drinkers of tea or coffee

Total drinkers of tea or coffee = tea only + coffee only + both = 20 + 40 + 72 = 132.

Step2: Calculate neither

Total surveyed is 184. So neither = 184 - 132 = 52.

Answer:

92
