How many different ways can 3 cubes be painted if each cube is painted one color and only the 3 colors red, blue and green are available?( Order is not considered , for example , green,green, blue is considered the same as green, blue, green.)
Please post the explanation. Thanks In advance.
I think the ans for this should be 3^3 ie each cube can be painted in 3 colors. What is the OA ?
Hey ...if order does nt matter ...i dont think it can be 3^3 ..
All that matters is choosing d diff set of colors ..
i.e choose 1 out of 3 colors OR 2 out of 3 colors OR 3 out of 3 colors..
If the drama club and movie club are combined what % of the combined membership will be male? 1) Of the 16 members of the drama club, 15 are male. 2) Of the 20 members of the music club , 10 are male.
Well I came across this question in one test and the answer as mentioned is E i.e Statement 1 and 2 are not sufficient to answer this question.

Can some one explain me why is it E ?
I think bcos in statement 2, the number of members in music club and not movie club is given. Not sure though if its a typo. Pls confirm.
Hey the reason why it is E is because in the question they havent mentioned the number of people who are in both the clubs. That means this question can only be solved assuming the there is no intersection between the two clubs. I hope you got my point.
In case, Please do let me know I will explain it in a better way.

Hi!
The answer is E as explained by virus_rocks. Cause we only the figures for Drama and Movie club, there is no info about the common people in both the groups.
I have 1 problem here .Is it possible for someone to tell me the solution to this
if x/3 is an integer each of the following must be an integer EXCEPT :
(x+6)/6
(x-9)/3
(x+9)/3
8x/24
(x^4 - 81)/81
I got stuck between answer choices A and E
All help is appreciated .
Whenever you get such ques, always take two values for x and check for each option. the option which doesn't give the integer value, is your answer. In this case take x=12 and 3. on checking for all 5 options. we see it's only A for which the value doesn't come out to be integer. and yes as kp1811 said- E can be simplified to (x/3)^4-1. that solves the problem.
