CAT ~ VA + QA - Last Minute Revision!!

#Fun #Easy and #Conceptual 

Jerry the mouse is on a mission to save his feathered friend, Tweety, the little bird. On his way he passes through a long straight drain pipe. After covering a third of the length of the pipe, Jerry turns around and notices Tom, the cat, approaching the entrance of the pipe, at a certain speed. He figures that to escape from the cat he could run towards the entrance of the pipe, at his usual speed, and jump out of the pipe just in time, before Tom arrives at the entrance. Alternatively, he could run towards the exit of the pipe, at half his usual speed, and save himself just in time, before Tom catches up with him from behind at the exit.


Find the ratio of the usual speed of Jerry to that of Tom.

a)1 : 1

b)4 : 5

c)3 : 4

d)Cannot be determined


At the same moment that Jerry notices Tom, he also notices another cat Tim, approaching the exit of the pipe at a constant speed. If Jerry figures out that he could save himself just in time by running towards the exit at his maximum speed, which is thrice his usual speed, or by running towards the entrance at a speed 20% higher than his usual speed, then find the ratio of the speed of Tim to that of Tom.

a)9 : 1 b)1 : 1 c)3 : 2 d)18 : 1

can someone plz post clock problems....to find the angles between hour and minute hand...

Samba has not been able to capture Veeru and Jay. To set an example to the rest of the dacoit gang, Gabbar decides to punish Samba for this. Nevertheless Gabbar wants to show Samba some sympathy because Samba has eaten Gabbar's 'namak'. Gabbar decides that he will fire two shots at Samba's temple from his revolver. Which of the following strategies, if adopted by Gabbar, will result in the highest survival chances for Samba?

A)

Gabbar places two bullets into a six-chambered revolver in successive order. He will spin the chamber, close it, and take one shot. If Samba is still alive, then he will take the next shot without spinning.

B)

Gabbar places two bullets into a six-chambered revolver in successive order. He will spin the chamber, close it, and take one shot. If Samba is still alive, then he will spin the chamber again before shooting the next shot.

C)

Gabbar places two bullets into a six-chambered revolver at opposite ends. He will spin the chamber, close it, and take one shot. If Samba is still alive, then he will take the next shot without spinning.

D)

Gabbar places two bullets into a six-chambered revolver at opposite ends. He will spin the chamber, close it, and take one shot. If Samba is still alive, then he will spin the chamber again before shooting the next shot.

  2. Real democracy is about mediating the popular will through a network of institutional structure and the law of the land.
  3. While law making and governance are meant to articulate the latter, the judiciary is supposed to protect the former from any kind of excess that might occur, unwittingly or otherwise, in the conduct of legislative and governmental functions.

3 days to go...feeling a little bit nervous. One moment, I feel that chances are very less considering the terrific competition that exists (Realised this after seeing the awesome scores of people in SIMCATS. 200+?? Seriously???)

The next moment I feel that it doesnt really matter. Who wants to be a topper anyways.

Then I think about normalisation and the cycle repeats. GODDAMNIT!!! 😠 :(

how to break such series ?

1/1 + 1/3 + 1/6 + 1/10 + 1/15 ............ infinite terms?

how ? 😲

1.2 + 2.2^2 + 3.2^3+................ +100.2^100 ? 

A sincere request to everyone who is posting questions here.

Please make sure you give OPTIONS while asking a question.
