Mera is baar Qa mei bhi happy birthday ho gaya. VA mei toh hota hi hai. QA: 16/4 (44)VA: 14/9 (33)1 ques didnt get registered in qa.saw it after the test. should be easily +3. 2 ques toh samajh aa gaye konse wrong hai. pole wala and area of triangle i also marked as 50. Rest 2 I dunno which ones...bad performance by me..

@RoadKill said: @Ibanez It would be clearer if you draw the pole waala figure. Let A be initial position making 30 degrees with the pole, let B be the final position making 60 degrees with the pole. AB = 30 root(3). Now, your 45 waala answer comes when B is between A and the pole. But there is another case where the pole lies between A and B, and here the height is 22.5. The question asked for min possible height.

@KaranGarcia said:

The 1st two questions in that set was easy and was unambiguous...but the 30 question was ambiguous in my opinion...Did anyone else get answer for that???

@cool2 said: @Ibanez 30root3 is the horizontal distance considering he doesn't cross the pole we get 45 but considering he crosses the pole since sum of angles from 1st view point and second view is 30+60=90 and taking the pole is vertical it is right angle at the bottom we will get right angle between(1st view point,top of pole and second view point)so 30root3 becomes hypo and distances from the top of poles and view points as the sides

yes, wasted time and left this one. weird combinations.

@2ndApr2011 said: Hello people , i know most of you must have solved the machine and bat wala LR set

(though i didn't even have a proper look at it ) , i solved it after my test was over , just wanted to check if the answers i got are correct . I have attached the problem for your reference .

25th ---> 16 Option c

26th ---> 24 Option c

27th ---> 18 Option a

P.S : The remainder of the problem is continued in the second attachment along with the options for the second question .

@[459739:Ibanez] :shrug: I would use "a" in most cases I guess. Part might be an exceptional case, now that I think about it.. "I am a part of this team" and "I am part of this team" both seem fine, but my instinct lean on the former...In the former case, I guess there is a bit more stress on the fact that there are other parts as well, but chhodo kya speculate karna on grammar. Nahi pata to nahi pata. But anyway, in "dealing heavy blow" versus "dealing a heavy blow", the first case is wrong because of the singular "heavy blow" following the verb..

ne one has the snapshot of the romanticism rc?? didnt have time to attempt it in the mock..

@CATASSTROPHY said: romanticism wala RC kya tha dost lok????? left me totally confounded.

Quant looked deceptively easy.. or was it actually easy?? my score doesnt tell the same story.

QA/DI :- 40(17/11)

VA/LR :- 50(20/10)

OA :- 90.

I'm really not sure what happened in quant. :-s

@RoadKill said: @techsurge Grammatically speaking, there should be "a" between "deal" and "heavy blow". But having observed TIME's way of thinking in most solutions, they are not always so heavy on grammar in these phrasal word usages. They usually look at outright wrong usages of phrasal verbs.. Ofc, I might be proven wrong, VALR hai after all...

@Ibanez said:

Height of the pole came out to be 45 for me.

@Ibanez said:

ya this is the one I marked. "deal heavy blow" seems weird.

@cool2 said: m=-5 or -1/5 since it is given the line has integer co-ordinates to get the maximum X co-ordinate there should be least increase in Y so one co-ordinate will be (0,6) and the other will (30,0) vice versa we get another case (0,30) and (6,0)

For height of the pole sum for the least possible Height one has to cross the pole and taking this condition we get a right angle triangle whose angles are 30-60-90 and hypo=30root3 and the height of this triangle hypo as the base will be 22.5

For quadratic equation problem the equation can be either x^2-5x or -x^2+5x so constant can be 6 or -6(i think so)

@techsurge said: @Ibanez

this one I believe " This unseasonal rains will deal heavy blow to the farmers. "

doesnt dealing with is used with people rather than situations...... not sure... just a hunch

@[459739:Ibanez]

@[349702:techsurge] Well, if you have doubts in VA, it is probably wrong.. At least, that is the rule that has worked for me in most cases. Anyway, I think this usage of deal is fine. Galat waala kaun sa mark kiya maine wo nahi yaad..

m=-5 or -1/5 since it is given the line has integer co-ordinates to get the maximum X co-ordinate there should be least increase in Y so one co-ordinate will be (0,6) and the other will (30,0) vice versa we get another case (0,30) and (6,0)

@YouMadFellow said:

You are directly applying b = h .. but this is true when they are independent of each other... Here they are dependent on a single variable that is the slope of the line... so you need to find a single equation containing "m" as the variable..

But, here the maximum depends on another factor that is integer co-ordinates.. so the possible value of m = 1, -1, 5, -5 .. For m = -5 .. we get the maximum by trial and error

@Omkarp said:

I thought the equation will be of the form ax + by = cArea = 0.5b*h.. This will be max. if b=h, so 10,0 and 0,10 should be the points. 10*10*0.5 = 50?This way?

@needabc said:

even i got 90...

@YouMadFellow said:

20th I was getting 90

(y-5) = m*(x - 5) -> x intercept => y = 0 -> x = 5 - 5/m

y -intercept => x = 0 -> y = 5-5m...

Area = 1/2 * (5-5m)*(5-5/m) ... For m = -5 (integer co-ordinates.. so m should be factor of 5).. I got 90..

@YouMadFellow said:

16) will it be 35 or 70??? the statement that in how many ways EITHER of them could win it confused me.....if we have to consider bth then 70....but i thot its just either of them...so marked 35...... hate such questions when u know the method to solve it and yet they are a little ambiguous
