From the given equation x + y = 32 --- eq 1 or -x -y = 32 ---- eq 2 Stmt 1 says -4x -12y = 0 or x + 3y = 0 ---- eq 3 Solving eq 1 and 3 we get x = 48 and y=-16 solving eq 2 and 3 we get x = -48 and y = 16 In both the above cases xy is same hence stmt 1 is suff. Doing the same exercise for stmt 2 giv...

One approach to solve this question is - total no of ways of selecting 3 people from 8 = 8C3 = 56 Now if the siblings are present in the combination then 2 places are booked and only one place is left to be filled.... 1*1*6 for each sibling pair..We have 4 pairs ...so total number of combinations in...

I think it is E, as the passage says that the govt most probably is responsible for the death

Well here is the ans: 1. xyz < 0 suggests only one of them is -ve. 2. xy <0 suggests x and y lies on two sides of the origin or zero. So lets draw the number line, and add both the constraints. |-----------X--------------------------0-----------Y---------------------------------| Now Z has to be pos...

There is another way to look at this problem. The box contains exactly the same number of even and odd numbered balls (50 each). Since we are replacing the ball after each pick , so the sum of the numbers of the balls picked will either be odd or even with equal possibility irrespective of the numbe...

{9}=3*9=27
{6}=6/2=3
{9}*{6}=27*3
so, 27*3 is of the form 3*m={m}
{9}*{6}={27}(ANS)

IMO E

As per the basic time work rule ....

1/A+1/B = 5/6

1/B+1/C = 2/3

1/C +1/A = 1/2

Adding the above 3 equations we get

1/A+1/B+1/C = 1
