Read Solution (Total 32)
-
- A+B+C=3000
So, (A+B) = 3000-C
C=1/2(A+B)
C=1/2(3000-C)
Solving the above equation we get =
3C=3000
C = 1000 - 8 years agoHelpfull: Yes(12) No(2)
- A=2/3(B-C) SO 3A=2B-2C &
C=1/2(A+B) SO 2C=A+B
A+B+C=3000
2C+C=3000
C=1000 - 8 years agoHelpfull: Yes(7) No(0)
- C = 1/2(A+B)
so, 2C = (A+B) --(1)
and given A+B+C = 3000 --(2)
now, combining (1) and (2)
2C+C=3000
3C=3000
C=3000/3
we get, C=1000 - 7 years agoHelpfull: Yes(5) No(0)

- Ans. is 1000.
- 8 years agoHelpfull: Yes(0) No(1)
- 2C=A+B (2nd equation)
Adding C to both sides
2C+C=A+B+C Since(A+B+C=3000)
3C=3000
Ans: C=1000 - 7 years agoHelpfull: Yes(0) No(0)
- A+B+C=3000 (GIVEN)
SO
A+B=3000-C
PUTT VALUE OF A+B IN
C=1/2(A+B)

- Is any body get the tcs offline call leter and suppose date to be held
- 7 years agoHelpfull: Yes(0) No(1)
- A+B+1/2(A+B)=3000
3(A+B)=6000
A+B=2000
So C=1000 - 7 years agoHelpfull: Yes(0) No(0)
- since C=1/2(A+B)
=>2C=(A+B) ---(1)
A+B+C=3000 ----(2)
now, putting the value of (A+B) from equation (1) in equation(2)
2C+C=3000
=>3C=3000
hence,C=1000 - 7 years agoHelpfull: Yes(0) No(0)
- A+B=2C
A+B+C=3000
2C=3000
C=1000 - 7 years agoHelpfull: Yes(0) No(0)
- A+B+C=3000
A+B+1/2(A+B)=3/2(A+B)=3000
A+B=2000
therefore, c=1000 - 7 years agoHelpfull: Yes(0) No(0)
- A+B+C=3000
So,A+B=3000-C
C=1/2(A+B)
C=1/2(3000-C)
Solving above equation we get
C=1000 - 7 years agoHelpfull: Yes(0) No(0)
- Since A+ B= 2C
And A+B+C= 3000
->2C+C=3000

- Answer, C=1000
Explanation
-----------------
We have,
C=1/2(A+B)
=>2C=A+B ---(1)
A+B+C=3000 ---(2)
From equation (1) and (2)
we get
2C+C=3000
=>C=3000/3
=>C=1000 - 7 years agoHelpfull: Yes(0) No(0)
- C=1/2(A+B)
A+B=2C
A+B+C=3000
In place of A+B in above equation put 2C
2C+C=3000
Ans C=1000 - 7 years agoHelpfull: Yes(0) No(0)
- 34 is the ans
- 7 years agoHelpfull: Yes(0) No(0)
- c=1/2(A+b)
2c=a+b
2c=3000-c
3c=3000
c=1000 - 7 years agoHelpfull: Yes(0) No(0)
- a+b+c=3000
a+b=3000-c
c=1/2(a+b)
c=1/2(3000-c)
2c=3000-c
3c=3000
c=1000 - 7 years agoHelpfull: Yes(0) No(0)
- A=2/3(A+B)...........(1)
C=1/2(A+B)...........(2)
From equation 2 we have 2C=A+B,substitute this in A+B+C=3000
2C+C=3000,=1000 - 7 years agoHelpfull: Yes(0) No(0)
- A+B+1/2(A+B)=3000
2A+2B+A+B=3000*2=6000
3A+3B=6000
A+B=2000
A+B+C=3000
C=3000-2000=1000 - 7 years agoHelpfull: Yes(0) No(0)
- Ans : 1000
we get after solving the equations as
A=2c-4x/2
B=2c-2x
c=5x
after substituting c we get A=2x
B=8x
C=5x
by calculating we get
c=1000. - 5 years agoHelpfull: Yes(0) No(0)
- C= 1000
Replace value of C in A+B+B = 3000 AND YOU WILL GET 3(A+B) = 6000 => A+B = 2000
REPLACE A+B IN C AND YOU WILL GET 1000 - 5 years agoHelpfull: Yes(0) No(0)
- IN THE QUES GIVEN THAT :- A+B+C=3000
Then we take the value of A+B from the above equation,then we get A+B=1000-C.
Put the value of A+B in this equation C=1/2(A+B)
: We get C=1/2(1000-C)
solving the equation we get=
2C=3000-C
3C=3000
C=1000. - 5 years agoHelpfull: Yes(0) No(0)
- c=3000-(a+b)
we know that , c=1/2(a+b) ---> 2c=a+b
c=3000-2c
c=1000 - 1 year agoHelpfull: Yes(0) No(0)
