Just trying to do one of these fund raising type quiz things and I`m stuck on this question(possibly a trick question)

What`s is 30% of 40% ?

[ali]

12%

[itexuk]

Yes 12%

[748IOM]

Computer says no...............................or in this case 12%.

[guest1]

and for all you non-believers stand to be amazed:
30% of 40% is the same as (drum roll)........40% of 30%
WOW. I am truly a magician.

[sparkin]

How did you get 12% you Carol Vordamens?

Alan I`m confused,explain please?

[psychlist]

30% is 30 parts of an item split into 100 parts. 100/30 = 0.3
40% is 40 parts of an item split into 100 parts. 100/40 = 0.4

so 30% of 40% is :-
30 parts of (40 parts of an item split into 100 parts) = 100/30(100/40) = 0.3(0.4) = 0.3 times by 0.4 = 0.12 = 100/12 = 12%



Shocking I know, but the same really DOES go for 40% of 30%

[748IOM]

30 * 40 / 100 = 12
