A) 8 years 
B) 20 years
C) 30 years
D) 35 years

Solution:

According to the statements

Let Ali's age 10 years ago = x

then Bilal's age 10 years ago = 2x 

(x+10)         3
-------    =  ------

(2x+10)      4

4(x+10) = 3(2x +10)

4x + 40 = 6x + 30

4x- 6x = 30 -40

- 2x = -10

x= 10/2

x= 5

Total of their present ages= 

=(x+10 + 2x + 10)
