Of 360 consumers polled some purchased ice cream some purchase frozen yogurt and some purchased both if 260 people polled purchased ice cream and 250 purchased both ice cream and frozen yogurt how many people purchased frozen yogurt?

Answer 1

Total customers are = 360

Number of polled people who purchased ice cream = 260

Number of polled people who purchased both ice cream and yogurt = 250

Hence, people who purchased only ice cream are=$260-250=10$

And $360-10=350$ are people who purchased yogurt.

So, people who purchased yogurt only = $360-(250+10)=100$
