Answer 1

Answer:

26

Explanation:

21 pizza, 28 partis(5 eat Pizza too) so only 23 eats only pattis OK, 30 burger(10 eat pattis +10 partially) means only 10 eat burger and 10 eat rice.

so total eating... 21pizza +23 pattis+10 burger+10rice=64.

so people don't eat any thing =26

Answer 2

Answer:

Required number of employees do not eat any food are 26.

Explanation:

Here given,there are 90 employees in an office.

So,total number of employees are 90.

Now, 21 employees eat Pizza

So, number of employees who eat only pizza $= 21$

28 employees eat Patties including 5 who eat Pizza.

So, number of employees who eat only patties $= 28 - 5 = 23$

Again,30 employees eat Burger including 10 who eat Patties, but not Pizza.

Therefore number of employees who eat only Burger $= 30 - 10 -10 = 10$

And 10 employees eat rice but not eat junk food.

So, number of employees who eat only rice $= 10$

It is also given that remaining number of employees does not eat any food.

So, required number of employees do not eat any food

$= 90 - (21 + 23 + 10 + 10) \\ = 90 - 64 \\ = 26$
