10 years back, Latha was half of Uma's age. If the ratio of their present ages is 3:4, what will be the total of their present ages?

**Answer**

May the present age of Latha and Uma be 3x and 4x

10 years ago, Latha was half of Uma's age

(3x-10) = 1/2(4x-10)

6x-20 = 4x - 10

2x = 10

x = 5

Sum of the current ages:

3x+4x=7x

7x = 7*5= 35
