Answer:

20 members have both hymn books and bibles.

Step-by-step explanation:

Sets

There are two sets of people. One is made up of members who have hymn books, the other one is made up of members who have bibles. From the total members of the congregation, some have neither.

The congregation has 300 members out of which 100 don't have bibles either hymn books. This means that 300-100= 200 members have bibles or hymn books. Since 130 have hymns books and 90 have bibles, there are 90+130=220 members who have either.

The difference of 220 - 200 = 20 is the number of members who have both hymn books and bibles.
