Answer 1

B:10Step-by-step explanation: 115 = 90+65+75-20-55-xx=30  

Answer 2

The number of residents who like at least two shakes is 85.

Given,

Total residents = 120.

Residents who like mango shakes = 90.

Residents who like banana shakes = 65.

Residents who like strawberry shakes = 75.

Residents who like only one of three shakes = 30

Residents who like two of three shakes = 55.

Residents who do not like any of the shakes = 5.

To Find,

The number of residents who like at least two shakes.

Solution,

Let the number of residents who like to have at least two shakes or more be x.
Number of residents who like the shakes = total residents - residents do not like any of the shakes

= 120 - 5 = 115

So,

115 = 90+65+75-30-55-x

x = 230 - 200

x= 30

Now, 55 like only two of the three shakes.

x = 55+30 =85.

The number of residents who like at least two shakes is 85.
