ReplyDeleteplease check this question in pieas test question no. 4

ReplyDeletecorrect if it's wrong,plz plz

f(x+1/x)= x-1/x => solution is,

let f(x+1/x) = y,

then,

y=x-1/x

y=[x^2-1] / x

xy=x^2-1 (By cross multiplication)

taking derivative on b.s;

x.dy/dx+y = 2x-0

or, dy/dx=[2x-y] / x

as dy/dx=f(x), and putting the supposition,

so, f(x) = [2x-(x-1/x)] / x

=[2x-x+1/x] / x

=[x+1/x] / x

=[(x^2-1)/x] / x

=[x^2-1] / x^2 (answer)

good work (y)

ReplyDeleteanswer of q no.1 is 6 ampere by p=IV

ReplyDeletephysics: question no. 7 = k , opption # c

ReplyDeletephysics; q # 9 = infinite images and q # 10 = yellow color

ReplyDeletefrom f(x) = [2x-(x-1/x)]/x

ReplyDelete=[2x-x+1/x]1/x

=1/x[x+1/x]

=1/x[x^2+1/x]after taking LCM of the terms in bracket

1/x(1/x)[x^2+1]

x^2+1/x^2 ans

plz english portion kai ques kai ans bata dain

ReplyDeletethe answer is x - 2/x

ReplyDeletePLEASE SIR IN KE ANSWER KEY SEND KAR DAIN

ReplyDeletetry once on ur own, if u have any problem in any question you can ask

ReplyDeletecan you please tell me from where should i prepare for the entry test of pieas

ReplyDeletetotal kitna ques hn ga pieas test ma???

ReplyDeletepieas test is quite general.. no need to prepare it.. just make your concepts strong

ReplyDeletedo we study our course books from first year and second year

ReplyDeletethanks

ReplyDeletesorry yah you r right

ReplyDeleteyup

ReplyDeletei think the answer is 5A. bcoz 6 bulb of 100 watt. that means total power is 600 watts and then when we use P=VI I=P/V =600/120 = 5 A

ReplyDeleteharis is correct

ReplyDeletephysics portion question 2,3,4

ReplyDeleteIts not the correct answer!

ReplyDeletePutt f(x+1/x) again in ur answer its not equal to (x-1/x)!!!!!

Its not the correct answer!

ReplyDeletePutt f(x+1/x) again in ur answer its not equal to (x-1/x)!

Its not the correct answer!

ReplyDeletePutt f(x+1/x) again in ur answer its not equal to (x-1/x)

asa tub ht hy jub function inverse me ho

ReplyDeleteits correct answer is x check out

ReplyDelete100 25 each

ReplyDeletePlease explain maths question no. 5

ReplyDeleteI think the question is a little wrong.. Firstly it says 2 m and 9 cm, different units and then no units in the answer so one can't really decide which unit to give ans in..

ReplyDeleteAnswers are a must to know if you've solved it right or not...Please upload them or take the test down kindly..

ReplyDeletepassing marks kitny hen pieas test may ??

ReplyDeletemay be...plz tell me the answer if anyone knows

ReplyDeletein q no. 6 in maths answer is option (a) -4/3 (14)^1/2

ReplyDeletedepends on merit list .if merit is high then high marks if low then lower...

ReplyDeletemaths q no 13 answer is d= o , zero distance is the minimum distance between the parallel lines.

ReplyDeletein q no 14 if question is correct like x^2+y^2+2x+6y=0 then answer will be y+1=0

ReplyDeleteyup sorry..

ReplyDeletephysics portion q.no.2 solution: work(input)=F.S = 50N. 5m=250J

ReplyDeletework(output)=F.S=240N.1m=240J

And as effeciency%=work(output)/work(input)=(240J/250J)x 100=96% efficiency

pieas negative marking?

ReplyDeletemaths portion q no 4 ans n solution?

ReplyDeleteThe answer of Q:3 in maths is 26.33333333...

ReplyDeleteAnswer written out there in apparently round off!

100

ReplyDeleteyes

ReplyDeletecan u plz upload chapter vise weightage of PIEAS entry test.............. i can'nt afford acadmey so thats why i am preparing it at home,,,,,,,,,,,plz do sommething in this regard

ReplyDeleteno, it can't be zero.. that's the trick lady

ReplyDeleteWell!! radius of sphere would be [(9/2pi)+2] = 3.43 = 3 (approx)

ReplyDeleteWell!! radius of sphere would be [(9/2pi)+2] = 3.43 = 3 (approximately)

ReplyDeletehey listen i m behzad
