    56 people drink 3 cups daily

    Step-by-step explanation:

    What's the total number of people that drink 3 cups?

    Total number of people = 400

    7 / 10 were asked said yes

    Number of people that said yes = (7 / 10) * 400 = 280

    280 people drink tea.

    20% of 280 people drink 3 cups daily, whats the number = ?

    20% of 280 = ?

    20 / 100 = x / 280

    (20 * 280) = (100 * x)

    5600 = 100x

    X = 5600 / 100

    X = 56 people

    56 people drink 3 cups of tea daily.
