Answer 5

you have to make a venn diagram for solving it
I am uploading the diagram, pls wait

Answer 6

Oh great, thanks
I thought i lost you on here..lol

Answer 7

here it is lol
inside the circles there are the no. of people who only take the bus or subway and in the intersection of the circle are the people who take both of them.

Answer 8

did you understand it yet?

Answer 9

Yes, I do; thank you so very much

Answer 10

Thanks to the diagram...it really helps..

Answer 11

you're welcome :)

Answer 12

Okay, it was very helpful, but for some reason I can't see how you got the other answers..i really want to understand..brain not working

Answer 13

umm, okay in the question it tells you the no. of people going from bus and subways right
like for bus-12 and subway-18 right? it is telling you how many people used bus and subway but it isn't telling how many of them used both

Answer 14

Right

Answer 15

the no. of people who used both is given 7 so you need to deduct 7 from the no. of people who traveled from bus and subway that is, 18-7=11 and 12-7=5

Answer 16

because the people who went with both the transport ways got mixed up with the people who went from only one of them so you need to subtract them from the nos. gives to you

Answer 17

just see the diagram, the people who went only from bus are 5 and the no. of people who only went from subway are 11

Answer 18

please do tell me if you didn't understand

Answer 19

Okay, i'm trying here

Answer 20

According to the diagram, (b) take only the bus would be 11

Answer 21

Take only subway would be 5

Answer 22

7 would be (c) either

Answer 23

And (d) 50-18-12=20

Answer 24

(c) would be 11+5=16

Answer 25

and you miscalculated (d)

Answer 26

13? 50-18-12-7=13

Answer 27

nono you did it right but 50 -12-18 is 10

Answer 28

My calculator says 20 which is why i'm confused

Answer 29

oh yeah i m really sorry my bad :P
