Column A: 100,210*90,021 Column B: 100,021*90,210 A (100,000+210)*(90,000+21) B (100,000+21)*(90,000+210) compare both B>A

for x= 1/100 y> 100 and for integers 1,2,--9 y Ans D

Ans 6^5

y=+/- x => y is between -5 and 1

Probability of getting the line busy on each of the 4 days= 2/3

area of rug = 1/2*9*12 let dimensions of rug are a &b, which are in the ration of the floor => a/9=b/12 => a=3*b/4 area or rug = a*b=54 solve this u'll get long side =option D

1. A 2. colA= 4x-60 colB t+40 ??? ans D 3. C

my bad the ans is C .

If x>0 an y>0, 1/x + 1/y = 3 ColA: 3xy Col B: x+y Ans D

oh i read it wrong ...my bad Q is asking month after 400 months... it is October

Given a square with vertex ‘O’ and centre ‘C’, when rotated by 45degree with respect to vertex ‘O’ the centre is changed to ‘C1’. Col A: Distance between centre’s ‘C’ & ‘C1’ Col B: {5*sqrt (2)}/2 oc= 5sqrt(2)/2 oc1= 5 sqrt(2)/2 angle coc1= 45 sin(45)= oc/cc1=1/sqrt(2)=> cc1=5 ColA > ColB

20. Now if the month is June, then what is the month after 400 months? Ans September 400 = 12*33 + 4

Roy is now 4 years older than Erik and half of that amount older than Iris. If in 2 years, Roy will be twice as old as Erik, then in 2 years what would be Roy's age multiplied by Iris's age? a) 8 b) 28 c) 48 d) 50 e) 52 ??
