Question 1112484: Age of mother is 2 times the age of her daughter, after 2 years the sum of their ages will be 49 years. the age of mother after two years will be ?
The literal translation to Math is THIS:
M = 2D (1)
(M+2) + (D+2) = 49. (2)
Substitute (1) into eq(2) to get
2D + 2 + D + 2 = 49
3D + 4 = 49
3D = 49-4 = 45 ====> D = = 15.
