@rohan_bhasker @pradyothcjohn Thanks guys. I am topper of CS at college and 5th rank at MG university. Do u guys have any idea if the university gives out certificates to ranks other than the 1st 3 ?
@joethaliath Thanks dude
tadaang .... my first ques ... posted in PG somewhere ... from time speed ( I dont know anything in this ) ...
Appu and Gappu both start running around a circular racetrack in the same direction, each of them going at a constant speed. Appu is on bicycle and Gappu is on foot. Appu goes all the way around the track and catches up with Gappu. The moment he meets Gappu, he turns around and heads back towards the starting point while Gappu keeps going on his path. When Appu reaches the starting point he again meets Gappu who is just finishing his first round.
The ratio of the speeds of appu and gappu?
1) 1+root(2):1
2) 2:1
3) 3:1
4) 4:1
5) none of these
ellaaavarkkum ente onaaaashamsakal 😃 enjoooy the sadhya
ps: @dead_alive i tried solving it , but couldnt arrive at a proper answer , where are the others??

its 1) (1+root(2):1)
in these type of questions u can assume the length of the track as unity.
also lets assume gappu travelled a distance of x, when they both meet for the first time.
First meet-
Gappu travelled - x
Appu travelled - 1+x
so ratio of their speed ( appu/gapu )= ( (1+x)/x ......(1)

Second meet
Gappu travelled - 1
Appu travelled - 1+2x
so speed ratio in this case = (1+2x)/1.......(2)
Since they move at constant speed....(1)=(2)
Solving 1 and 2 we will get x = 1/root 2
So the ratio of their speed will be 1+2x = 1+root (2)
Ellavarkkum ente hridhayam niranja oonashamsakal....
Bad luck for me this time..No mom made oona sadhya and payasam on this thiruvonam day....
Have a splendid day guys!! :)

Luks like the thread has lost a bit of the josh especially after Onam 
Let me try & breathe some life back into it..
1)If a, b, c, d are real numbers with a2 + b2 + c2 + d2 = 100, then what is the maximum value of 2a + 3b + 6c + 24d?
a)240 b)250 c)300 d)None of these
2) If one root of the equation (I-m)x^2 +I x + 1 = 0 is double of the other & is real, find the greatest value of m.
A)9/8 B)8/7 C)8/6 D)7/5 E)5/7
