5 % of the income of A is equal to 15 % of the income of B and 10 % of the income of B is equal to 20 % of the income of c. If the income of C is Rs. 2000. What is the total income of A, B and C?

A. Rs. 14000
B. Rs 16000
C. Rs. 18000
D. Rs. 12400
Explanation:
10/100 × B = 20/100 × c
=>B = 2c =>B = (2 × 2000) = 4000
5/100 × A = 5/100 × B =>A = 3B = (3 × 4000) = 12000
(A + B + C) = Rs (12000 + 4000 + 2000) = Rs. 18000
