Question

Rs. 3000 is distributed among a, b and c such that a gets 2/3rd of what b and c together get and c gets 1/2 of what a and b together get. Find c's share. 1. 1800

Answer 1

3000 is distributed among A B and C such that A gets 2/3 of what B and C together get and C gets 1/2 of what A&B together get find C share

 

A+B+C=3000                                       I 

A=2/3B+C

C=1/2A+B

 

A=(2b+2c)/3

3a=2b+2c

3a-2b-2c=0                                            II

 

C=(a+b)2

2c=a+b

-a-b+2c=0                                            III

 

A+B+C=3000           I 

3a-2b-2c=0             II

-a-b+2c=0            III

 

 

 

 

 

c=800 i got wrong answer where is my mistake and how to solve this correct equation
