or, B's income =Rs.4000

15% of B's income =15% of 4000=Rs.600

5% of A's income =15% of B income=600

Answer 2

Step-by-step explanation:

30/100*A=40/100*B

3A/10=4B/10

50% of B =70% of C

50/100*B=70/100*C

5B/10=7C/10

28x+21x+15x=19200

64x=19200

X=300

Income of C in ratio 15x

C=15*300

C=4500
