If Manvinder obtains 10% marks more then Sukhvinder then how many % less marks are obtained by Sukhvinder than Manvinder.

OPtion

1) 9
2) 9.08
3) 10
4) 9.9
5) 10.01
6) 10.1
7) 9.09
8) 9.8
9) 11
10)None of these

Solution

Let marks of Sukhvinder is x
Then according to given condition marks of Manvinder is 1.1x
Difference of marks is 1.1x – x = 0.1x
Hence marks of Sukhvinder are (0.1x/1.1x)*100 = 100/11 = 9.09 % less than marks of Manvinder.

option 7)

Correct Option: 7 Best Solution (42)

R.RAVIKUMAR   11 years AGO

let manvinder marks be x and sukhvinder marks be y
so, x=(1+0.1)y
so, y=(1/1.1)x
that is y=0.909x
so, y=(1-0.0909)x
so, y is (0.0909*100)=9.09% marks less than x.

Devendra Marghade   11 years AGO

If marks of Sukhvinder=x,Manvinder=x+(x*10/100)=1.1x
If 1.1x marks are considered as 100%
then x= x*100/1.1x= 90.90%
So % less=100-90.90=9.09

Ans: 7) 9.09
Let marks of Sukhvinder be x.Then marks of Manvinder is 1.1x

let sukhvinder obtained 20 marks

AMIT JAISWAL   11 years AGO

given that marks of manvinder is 10% more than sukhvinder,then
according to the formula-

=(10/110)*100%
=100/11=9.09

Abhijeet Kumar   11 years AGO

let
sukhvider got x marks out of 100 then
manvider marks would be [x+(x*10/100)]=(x+0.1x)
difference is (x+0.1x-x) = 0.1x marks
and (x+0.1x)= 1.1x
if (1.1x) is 100 perecntage
then 0.1x is (100/1.1x)*0.1x=(100/11)*1

In every case the sum of the first three letters is counted.

For WEDNESDAY, W =23, E = 5, D = 4, so, 23+5+4 = 32
For SATURDAY, S = 19, A = 1, T = 20, so, 19+1+20 = 40
For FRIDAY, F=6, R = 18, I = 9 , so , 6+18+9 = 33
For, MONDAY , M= 13, O= 15 and N= 14 , so, 13+15+14 = 42

Give numbers to each alphabets like A-1, b-2, c-3...w-23,x-24,y-25 and z-26
Now Add the first three letter of each day
like WEDNESDAY = W+E+D= 23+5+4 =32
SATURDAY = S+A+T = 19+1+20=40
FRIDAY = F+R+I = 6+18+9 =33
MONDAY = M+O+N = 13+15+14=42

27 Nov 2013 Speed

Two trains A and B are moving in opposite direction in different tracks. The length of these trains are 100 m. and 110 m. respectively. If speeds of A and B are in the ratio 4:5 and these two trains cross each other in 10 sec. Then speed of train B is

OPtion

1) 70/3 m/s
2) 5/3 m/s
3) 50/9 m/s
4) 55/3 m/s
5) 35/3 m/s
6) 28/3 m/s
7) 4/3 m/s
8) 40/9 m/s
9) 84 m/s
10) 105 m/s

Solution

Let the speeds of the trains are 4v and 5v. Since the trains are moving in opposite direction,
relative speed of the train is 4v + 5v = 9v
According to the formula
speed = distance / time
9v = 210/10 = 21
or v = 7/3 hence speed of B is 5v = 5*7/3
= 35/3 m/s
option 5)

Correct Option: 5 Best Solution (34)

Raisul Alam   11 years AGO

As the speeds of A and B are in the ratio 4:5, so let the speed of A=4x m/sec and the speed of B=5x m/sec.
The trains are moving in opposite direction so the relative velocity will be (4x+5x)=9x m/sec.
The length of train A=100 m and the length of train B=110m. So if they crossed each other the total distance will be covered is (100+110)=210 m as they are moving in opposite direction.
Now, 9x m goes in 1 sec (given)
1 m goes in 1/9x sec.
210 m goes 210/9x sec.
So it is given that (210/9x)=10
Hence x=21/9.
So the speed of B=5*21/9=35/3. and option 5 is the right answer.

Suman   11 years AGO

As trains are running in opposite direction so their resultant speed will be sum of their speeds...
ratio of their speed is 4:5
let us assume their speed are 4x m/s and 5x m/s
resultant speed is 9x m/s
in 10 sec they cover 9x*10 i.e 90x m
According to the question 90x=210
x=210/90 i.e 7/3
So speed of train B is 7*5/3 i.e 35/3 (ans)

Converting the equation 14+[16/{(6*7)-(5/4)}] to the new sign becomes 14/[16+{(6-7)*(5+4)}] solving this equation according to bodmas gives answer 2. so correct option is 1.

DHIRENDRA    11 years AGO

given
5 + 5 = 1, 5/5=1,
5 - 7 = 35, 5*7=35,
8 * 6 = 2, 8-6=2,
8/4 = 12, 8+6=12,
on comparing +=/,
-=*,
*=-,
/=+,
now the expression is
14+[16/{(6*7)-(5/4)}]=?
now replace the operator with equivalant operator
and the new expression will become like this
14/[16+{(6-7)*(5+4)}]
now apply the BODSMAS rule
=14/[16+{(-1)*(9)}]
=14/[16+{-9}]
=14/[16-9]
=14/[7]
=14/7
