1.already given income of c,=Rs.2000
let x be the income of 'B'and'c'
2.now,income of B is=(10/100)*x=(20/100)*2000(since 10% of income B is equal to 20% of income c)
3.therefore, solving,x=4000 i.e)B=Rs.4000
4.likewise income of A is=(5/100)*x=(15/100)*4000(since 5% of income A is equal to 15% of income B)
5.therefore,A=Rs.12000
6.total of A,B and C is=2000+4000+12000=18000

(5/100)*A=(15/100)*B-----------eqn(1)
(10/100)*B=(20/100)*C-----------eqn(2) since income of c=2000 given
put value of C in eqn 2 we get value of B i.e B=4000
now put value of B in eqn 1 we get A=12000
now A+B+C=12000+4000+2000= 18000 ans
