Question

$5\%$ income of A is equal to $15\%$ income of B and $10\%$ income of B is equal to $20\%$ income of C. If the income of C is Rs.$2000$, then find the total income of A, B and C.

Answer 1

C's income $=Rs.2000$

20% of C's income $=Rs.400$

$10\%of{B}^{\prime }sincome=20\%of{C}^{\prime }sincome$

or, 10% of B's income $=400$

or, B's income $=Rs.4000$

15% of B's income $=15\%of4000=Rs.600$

5% of A's income $=15\%ofBincome=600$

Thus, A's income $=Rs.12000$

Total income of $A+B+C=12000+4000+2000$

$=Rs.18,000$
