any one can tell me negative marking of elitmus exam?

Like? Yes | No

Reply

vikram kumar 11 years ago

First of all negative marking is calculated in every section separately.
If u make upto 25 % of ur attempted question wrong then there will no negative marking.
for. eg if u attempt 8 questions out of which 2 are wrong ..then no negative marking..
and after that limit 50% negative marking for every question..
ie if u make 5 questions wrong out of 8 then , 2 question are under permissible limit (ie 25% of 8) and for rest 3 wrong questions 50% negative marking will be done.

1) 5 liters

Price of 15 litre @ Rs. 200/liter = 15*200=3000
Quantity of chemical required to make mixture Rs. 150/liter= 3000/150= 20
So quantity of water in mixture =20-15=5 liters

Then s.p for 15% profits becomes 23x/20...
s.p for 20% becomes 6/5(50-x)...
s.p on whole of 50kg becomes 117/2...

Assuming merchant sells x Kgs at 15% profit.
Profit of selling x Kgs at 15% + Profit of selling (50-x) Kgs at 20% = Profit of selling 50 kgs at 17%
x*115 + (50-x)120 = 117*50

selling price would be 180+180*20/100=216
so Marked price would be 216+45=261
CP+mark up=Marked Price
180+mark up=261
mark up=261-180=81
in 180 mark up is=81
then in 100 mark up would be=81*100/180=45%
which means 45/100=0.45
I hope you will get it.....:p:p:p:p:p:p

R-Rani's Weight
M=Meena's Weight
T=Tara's Weight
R=(25/100)M ----(1)
R=(40/100)T ----(2)
from (1) and (2)
(25/100)M=(40/100)T
M=1.6T
so 160%

i think option (b) is correct.. suppose train from mumbai central run with a speed of x... and 2nd one with a speed of y.... the train meet after running P km from mumbai central... then since the time taking to reach this point is same for both the train so..
(P/x)=((300-P)/y)
also it is given that
(300-P)/x = 9
and
P/y = 4...
solving these three equation u will get x = 20 and y = 30;
thanx..

after meeting the ratio of speed would be-
let for mumbai train speed is M and surat is S
M:S=sqrt(4):sqrt(9) i.e. 2:3
Now,both of the trains take 9 and 4 hours respectively.So,
let a proportional constant is k.
Then,9*2k+4*3k=300 i.e.k=10
it means the speed is 10*2=20 and 10*3=30 .
I hope you will get it.

Ankit i wanna just tell you that amcat exam scoring would be different rather than your expectation.
It scoring based on the time that you have taken to solve that question according to the level of difficulty of that question.
