A's capital is equal to twice B's capital and B's capital is three times C's capital. The ratio of the capitals is:

A's capital is equal to twice B's 

capital and B's capital is three 

times C's capital. The ratio of the

 capitals is:

(a) 2:1:3
(b)1:2:6
(c) 6:3:1
(d) 1:3:6

Correct Answer: c

Solution:

Let C's capital = x
B's capital = 3* C' s capital 
                = 3*x
A's capital = 2* B's capital
                =2*3x =6x
Therefore A:B:C = 6x: 3x: x =6:3:1
