Question

if 25% of the people in an office like only hot coffee and 40% like only cold coffee,then how many like both hot coffee and cold coffee?

Answer 1

35% people in the office likes both tea and coffee.

Answer 2

Answer:

35% people like both, hot coffee and cold coffee.

Given:

25% of the people in an office like only hot coffee and 40% like only cold coffee

To find:

how many like both hot coffee and cold coffee

Solution:

people in an office like only hot coffee = 25%

people in an office like only hot coffee = 40%

so, assuming everyone in the office atleast likes either hot or cold coffee, let the number of people who like both be y.

y = 100 - (people who like hot + cold coffee)

y = 100 - (25 + 40)

y = 100 - 65

y = 35%

Hence, 35% is the correct answer.
