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 = ...
Bro aapne ek baar jo bol diya OA wahi hota hai.
Namaskaar pankaj bhai!!

It is 1. 312211
Concentrate on how the numbers are said,
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.
312211
OA kya hai ?
For the M:N wala question it should be 3:2 as explained by arumugudas I think.
What is the next no. In below series?
1,11,21,1211,111221,?
1.312211
2.222211
3.311211
4.211211
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...
may be coz,i'd found myself understanding the problem:)
but really thanks a lot for your effort..
Another Q from geometry:
OA:5
P.S : Good Night,And Good Luck

12*(x+2) = 18x
24 = 6x
x=4
D=72
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
Gr8 move u gt it nice. M on mobile bhai u r absolutely ri8,by the way hw u got that i m on mobile.

Yeah,u're right
Son gains 6km over the father for an hour
Father has gained 12 km before the son starts
To catch up w/ father,the sons travels for 2 hrs,and again he has to take 12 Km lead so that father would travel for another one hour
so,the son has to travel for 4 hrs,so the dista...

you need two equation to solve this type of question
time taken to meet first time is same ....using this one equation can be formed
let distance be X
x-410/410=s1/s2
time taken to meet second time can be used to form second equation
note : ignore rest taken 1 hrs (beca...
