let the income of A = x Rs , B = y RS and C = 20000 Rs 

given that 

x $$\times$$5%} = y $$\times$$ 15%                                equation 1 

and 10% $$\times$$ = 20% $$\times$$ 20000                   equation 2 

solve eq 2 we get y = 40000 Rs 

put value of y in eq 1 we get x= 12000 Rs 

so the total income is =  120000 + 40000 + 20000 = 180000 Rs Answer
