Chicken Beef Total
Rice 20 10 30
Pasta 40 30 70
Total 60 40 100
Place given information into the chart...Total customers who like rice is 30 and 20 of the like chicken. This means the other 10 (30-20 = 10) must like beef. 60 customers liked chicken means column for chicken has a total of 60. Subtract and find how many like pasta 40 (60 -20 =40)...
Is this enough help or do you need clarification on the second problem?
