Question

the table above shows the distribution of blood type for two groups of people, group x and group y. each group contains 2,000 people. based on the information in the table, how many more people in group x have blood type a than in group y ?
answer

Explanation:

Step1: Calculate number in Group X with type A

Each group has 2000 people. For Group X, blood type A is 42%. So number is \( 2000 \times 0.42 = 840 \).

Step2: Calculate number in Group Y with type A

For Group Y, blood type A is 30%. So number is \( 2000 \times 0.30 = 600 \).

Step3: Find the difference

Subtract the number in Y from X: \( 840 - 600 = 240 \).

Answer:

240
