Question

An insurance company records on 1,000 insurance policy holders reveals the following information:

1) 220 purchased only disability insurance.

2) 110 purchased health and life insurance.

3) 330 purchased health insurance.

4) 100 purchased only life insurance.

5) 100 purchased disability and life insurance.

6) 470 purchased only disability, only health, or only life insurance.

7) 330 did not purchase disability, health, or life insurance.

Calculate the number of these policy holders that purchased life and health insurance but did not purchase disability insurance.

Answer 1

470 - 220 - 100 = 150 only health
330 - 150 - 100 = 80 health and disability
220 + 100 + 80 = 400 disability
1000 - 400 - 330 - 150 - 100 = 20 that purchased life and health insurance but did not purchase disability insurance.
