Download Placement StatsI guessed this one would be option five because the answer would be 12+a*sqrt(b) :sneaky:

And only option5, has that form. But is there a better way to do this? Something conceptual?

Another Q from geometry:

OA:5

P.S : Good Night,And Good Luck

I guessed this one would be option 5 because the answer would be 12+a*sqrt(b) :sneaky:

12 because AE + ED = 12, and the other side would be a*sqrt(80)

And only option5, has that form. But is there a better way to do this? Something conceptual?

P.s. Encleadus = Saransh bhai? and Pkaman = faad pankaj kamani?

This is just counting the number of 1's and 2's.

3 times 1 then 2 times 2 then 1 time 1.

So, 312211.

devanshu97 SaysA and B pick up a ball at random from a bag containing M red and N yellow colored balls one after the other replacing the ball everytime till one of them gets red ball. The first one to get a red ball is declared the winner. If A begins the game and odds in favor of his winning the game are 3 to 2, then find the ratio of M:N

i might be wrong ....

i am trying because u asked ........ask jain bhai or varun thaygi ..........

odds in favour = p(E)/p(E') =3/2

its written who gets the red ball will win so winning for A is 3/x and and not winning is 2/x ...here wat is x total no of balls 3 red and 2 yellow ie 5 balls

since the balls are replaced before every draw it remains 5

so M:N =3:2

tell me the ans ...check pls:)

the question says father has to travel 2 hrs more than son

diff between their speed is 6 km

so 6*4 = 24 km which will make the father to travel two hrs more

so 18*4 = 72 km
