Question

In a ceremony, out of 800 participants, 620 drank milk, 350 drank tea. If 50 did not drink any of them, find out how many people drank at least one drink.​

Answer 1

Answer: 750

800-50= 750

Step-by-step explanation:

This is a trick question, as some of the participants may have drank both the drinks. But, we know that 50 didn't drink anything. Hence, 750 people drank at least one drink.

Answer 2

Answer:

530

Step-by-step explanation:

total amount of people= people who drank milk +people who drank tea+people who did not drink tea nor milk-x

x is number of people who drank two milk so

x=220

people who drank two drinks+people who drank none+people who drank 1 drink=800

220+50+y=800

y=530
