Question

There are 210 members in a club, 100 of them drink tea and 65 drink tea but not coffee. find.. i) how many drink coffee ii) how many drink coffee but not tea​

Answer 1

Total number of members = 210.

Number of members who drink tea = 100.

Number of members who drink tea but not coffee = 65.

Number of members who drink tea and coffee = 100–65 =35.

Let number of members who drink coffee = x.

Then number of members who drink coffee but not tea. = (x-35). , accordingly :-

x + 100 -35 =210.

x = 210 +35–100.

x = 145. , thus , number of members who drink coffee = 145.

who drink coffee but not tea = (x-35) =145–35 = 110. Answer.

Answer 2

Answer:

i.) 100 drink coffee       ii.) 35

Step-by-step explanation:

i.)  so 100 drink tea and coffee because they did not specify but 65 only drink tea but the rest are probably drinking coffee. so basically 100 is the answer for i because we said that 100 drink tea and coffee. For ii, It does not specify anything in the question but I think they drink coffee. So you take 100 and add 65 because so you know that total that drinks tea (which is 165). Then you subtract 165 from 210 which is 35. So the answer of ii is 35
