The ratio of ages of two persons is 5 : 9 and the age of one of them is greater than the other by 40 years. The sum of their ages in year is?

Present ages of 'A' and 'B' are in the ratio 3:5, respectively. Present ages of 'B' and 'C' are in ratio 2:3, respectively. If five years hence from now, age of 'A' will be 54% less than that of 'C', then find the present age of 'C'. a. 45 years b. 20 years c. 30 years d. 48 years

The ratio of the present ages of A and B is 3 : 7, whereas after n years it will be 1 : 2. Find the difference between their ages after 2n years, if the ratio of their ages 15 years ago was 1 : 4.
