5% income of A is equal to 15% income of B and 10% income of B is equal to 20% income of C. If income of C is Rs.2000, then total income of A, B and C is?
Correct Answer: Rs. 18000
Explanation:
∵ 5% of A=15% of B and 10% of B = 20% of C
∴ A/20 = 3B/20 and B/10 = C/5
⇒ B = 2C
⇒ A/20 = (3/20) x 2C = 3C/10 =(3/10) x 2000 = 600
∴ A = (600 x 20) = 12000,
B = (2 x 2000) = 4000
∴ A + B + C = (12000 + 4000 + 2000) = 18000
