for the 2nd attachment question also, i believe both the statements are needed to answer the question......

Pencil, pen eraser one:
(statement 1)*2-(statement 2)= 1 pen + 1 pencil + 1 eraser =10rs.
(statement 1)*2-(statement 2)= 1 pen + 1 pencil + 1 eraser =10rs.
So, both together together can give the answer :)
P.S.: Bro if possible, give a number to the question. Otherwise it won't be possible to recognize which one is answered.

ok Bro.....wll do it from next time....
@vbhvgupta said:Can u explain?
let A be the area of X and B be the area of Y
GIVEN-shaded area of X=0.25A
and shaded area of Y=0.4B
STATEMENT 1
0.25A=0.75*0.4B..........only one eqn two unknowns........no conclusion
STATEMENT 2
B=10
shaded area of B=0.4*10=4
no conclusion about A's surface area
COMBINATION of TWO STATEMENTS
shaded area of A=0.75*0.4*10=3.......hence conclusion is possible by combining

i donno whether this is answered or not.....my take: both the statements are necessary to answer this question....is it correct....?

11 mines are present in the figure..
E, G, I, K, L, M, P are not mines.. right ??

@vbhvgupta said:Q5
Can be answered by either of the statements.
[1] probability =1
[2] probability = C(2b, 1)/C(3b, 1)=2/3
.. 😃 @vbhvgupta said:Q5
i think, can't be answered using alone, both.. as other colors of balls are not mentioned..
1) no info of other color balls..
2) if there are red and green color balls also, then prob will be 10/20,
if there is only red color balls, then prob will be 10/15, etc..
1) no info of other color balls..
2) if there are red and green color balls also, then prob will be 10/20,

@vbhvgupta said:Q5
Statement II is enough
Statement I : No information on other colored balls Or rather total balls
Statement II: Ratio is given, so probability can be found.

See in the 2nd case, Red + Green = Balls which are not blue = 2*Blue
OR Red = balls which are not blue = 2*blue ... so it doesn't matters I think, ratio remains the same..

may be you are right 😃 and i think, you are..
i was taking it as twice of all sets of other color balls..

I think 1st is also enough p = 10/10 = 1
@vbhvgupta said:I think 1st is also enough p = 10/10 = 1
Nope... The statement just mentioned blue balls ... Nothing about total balls 😃
Q6 plz explain
@YouMadFellow said:Nope... The statement just mentioned blue balls ... Nothing about total balls
Consider it seperately means box contain 10 ball only....as in question nothing mentioned about other ball.......
I am not sure I am right....
@vbhvgupta said:Consider it seperately means box contain 10 ball only....as in question nothing mentioned about other ball.......I am not sure I am right....
If the statement were "The box contains only 10 blue balls" , it would have been fine. But it is incomplete I think. Waiting for the OA 😐 ..
