confusing math problem? easy but i am confused?

Wouldn't that be 210/2?

The word missing from the problem is each. How many did the couple invite each. Maybe they both invited the same number of people. Maybe they both agreed on inviting a total of 210.

Now that we have decided that the wording is indeed confusing, we will give an answer which we can be certain.

The couple invited an AVERAGE of 105 family members and relatives each.

The proper wording of the second sentence should be: If the couple each invited the same number of family members and relatives; how many did each invite?

If you find an ambiguous question, give the teacher the answer you think he/she is looking for and point out the ambiguity. You might get extra credit.

The confusion is caused because you're looking at irrelevant information. I'll write it with the piece missing;

210 are relatives and family members of the couple. if the couple agreed on inviting the same number of family members and relatives, how many did each invite?

Then it's simply 210/2 =105

The problem is not correctly stated.

For every 330 guests, the couple invite 210 relatives and family members. So, for every 1 guest, they invite 210/330=7/11 relatives or family members.

A reasonable question would be, If there are 1000 guests, how many are relatives and family members?

Ans. (7/11)(1000)=636.36 or 636 relatives and family members.

Assuming all of the invited came to the party.

210 relatives and family members / two people of the couple = 105 invites per person. I might be missing something if this seems confusing.

If 210 are relatives and family members of both the bride and groom, I would subtract that 210 from 330, which gives 120. That's the number of guests left to invite who are not related to both. I would then divide the 120 by 2, and I would say that each should invite 60. Another possibility is that since 210 people might be considered invitees of both the bride and the groom, you might add 210 to the 60, giving each side 270 guests (including those who are receiving invitations from both the bride and the groom.) The problem isn't worded very well, and I think it is made to trick you. I think my second paragraph is the answer to the trick. If there is no trick intended, it still isn't well-written, but then 60 would be the answer. Go prepared with both answers.

210 divided by 2 = 105

They were each allowed to invite 60 family members and friends.

105?
