why not A

Between D & E its D. In both the sentences they seems to be talking about government, which makes more sense in D

Imo B

Imo E

Answer will be A. Statement 1: If slope is negative the angle formed while intersecting with x axis is greater than 90 and now if you draw it you will understand why "Any line that has a negative slope will pass through both the 2nd and the 4th quadrant". Statement 2: There can be a line which passes through that point nad crosses I, IV III quadrant only

Imo E

It should be Xi = (Xi-1)/2 otherwise it doesnt make any sense. Ans C Statement 1: Xi = Xi-1 - 0.5 You can not make anything from this until and unles you know X2. Statement 2: X5 = X4/(X4 + 1) Again it only talks about X4 & X5 an dno values can be detected. If we combine both, X5 = (X4)/2 from Statement 1 Put this in Statement 2: (X4)/2 = X4/(X4 + 1) Hence X4 = 1 Using Statement 1 we can find that X1 will 2.5 Hence C

Got D too. My approach was: Given: C:B:F = 7:9:2 hence suppose F = x, then B = 9x/2 & F = 7x/2 Also remember x>5 Statement 1: 7x/2 + x x Hence as x > 5 x will be 6. With x = 6, C = 21 & B = 27 all integers. Statement 2: 7x/2 x As x > 5, x can be 6 or 7 We have already seen x = 6 holds good (in statement 1) If x = 7, C = 49/2 which is decimal and as number of chickens cant be in decimal 7 is not an answer. Hence D & x = 6

imo A

namit equation is x + (5/x) = 6 Hence when you put x as 5 you get both lhs = rhs = 6 Ans E

same as shoebite. Ans is C

Guys evenly divisible means thats the number when divides shouldnt leave any remainder. It doesnt mean it should be a multiple of 2. Hence A

Imo D

No I am not. I am sorry I wrote the wrong equation: Change the 2nd half time to: (100-x/100)*D/60 = (100-x)*D/6000 Hence overall equation is: = D/(x*D/4000 + (100-x)*D/6000) Sorry for the typo
