Among 200 people, 56% like strawberry jam, 44% like apple jam, and 40% like raspberry jam. if 30% of the people like both strawberry and apple jam, what is the largest possible number of people who like raspberry jam but do not like either strawberry or apple jam?

80

Step-by-step explanation:

only 40% of 200 people like raspberry jam, so that'd be

40% of 200 = 40/100 × 200 = 80

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
