( 5 % ) of ( A^{prime} s ) income ( =15 % ) of ( B_{s}^{prime} ) income ( 10 % ) of ( B ) is income ( =20 % ) of ( C^{prime} ) s income Let ( A^{prime} & ) income be ( a^{prime} ) and ( B^{prime} ) sincomebe'b' C's income ( =x^{prime}=frac{2000 mathrm{Rs}}{2} ) 100 [ begin{array}{l} begin{aligned} text { 8) } frac{10}{100} times b &=frac{20}{100} times c b &=2 c b &=4000 text { Rs } frac{5}{100} times a &=frac{15}{3} frac{15}{100} times b a &=3 b=3 times 4000=12000 R end{aligned} end{array} ] ( left.therefore a+b+c=18000 R s / text { option }-k^{3}right) )
