Mukesh has x dollars more than the amount Mohan has and together they have a total of y dollars. Which of the following represents the number of dollars that Mohan has?

OPtion

1) (y-x)/2
2) y-(x/2)
3) (y/2)-x
4) 2y-x
5) 2x-y
6) y-x
7) 2y/x
8) 2x/y
9) x+y
10) None of these

Solution

let mohan has P dollar
then Mukesh has p+x dollar
by the condition
p+x+p=y
2p+x=y
2p=y-x
p=(y-x)/2

Correct Option: 1 Best Solution (19)

Abhijeet Kumar   11 years AGO

Mukesh has X dollar more than the amount of Mohan
i.e
Mukesh = X + Mohan
so,
Mukesh - Mohan = X ----(1)

and Together they have Y dollar
i.e
Mukesh + Mohan = Y ----(2)

simplify equation 1 & 2

Mukesh - Mohan = X
Mukesh + Mohan = Y
- - -
-----------------------
0 -2Mohan = X-Y

i.e Mohan = (Y-X)/2

Ans is option (1)

Mokesh = X + Z
Mohan = Z
X + 2Z = Y
Z = Y-X/2

Mukesh=x+Mohan
Mohan+Mukesh=y
that implies: x+2(Mohan)=y
Mohan=(y-x)/2

Let mukesh and mohan has the amount be a,b respectively.
It is given that, b+x = a and a+b = y
i.e., b-a = -x ......(1)
and b+a = y .......(2)
Adding (1)&(2), we get
2b = y-x
b = (y-x)/2
Hence mohan has (y-x)/2.

Let Mohan has M dollars
then Mukesh's dollar=M+x
Total Mohan+Mukesh dollars= y = M+M+x =2M+x
Therefore Mohan's dollar=M=(y-x)/2

Martin Raj Kumar   11 years AGO

given Mu=Mo+x and
Mu+Mo=y
adding them
Mo+2Mu=Mo+(x+y)
Mu=x+y)/2
also Mo=Mu-x
so Mo=(x+y)/2-x
=(y-x)/2
thus,option 1

Anuj Pansari   11 years AGO

Let mohan has "m" amount,
thus, mukesh has = m+x
total = y,
mohan's + mukesh's amount = y
=> m + (m+x) = y
=> 2m + x = y
=> m = (y-x)/2

Lets Mohan have $p then Mukesh have $(p+x)
(p+p+x)=y, => 2p=y-x, => p=(y-x)/2
