An old lady spent one twelfth of her life as a child and one seventh w...
Explanation:

Given Information:
- 1/12 of her life as a child
- 1/7 of her life as a teenager
- 1/6 of her life between becoming an adult and getting married
- Daughter was born 3 years after marriage
- Daughter died 6 years before the lady died
- Lady lived twice as old as her daughter

Calculations:
- Let x be the total lifespan of the lady
- From the given information:
- Childhood: x/12
- Teenager: x/7
- Adult to marriage: x/6
- Daughter born 3 years after marriage, so lady's age at daughter's birth = x/6 + 3
- Daughter died 6 years before the lady died, so lady's age at daughter's death = x - 6
- Lady lived twice as old as her daughter, so x = 2*(x - 6)

Solving for x:
- x = 2*(x - 6)
- x = 2x - 12
- x = 12

Calculating Daughter's age:
- Daughter's age at lady's death = x - 6 = 12 - 6 = 6
- Daughter's age at death = Daughter's age at lady's death + 6 = 6 + 6 = 12
Therefore, the lady's daughter lived for 12 years. Hence, option c) 42 years is incorrect.

Let the age of the lady at the time of her death be X.
Age spent as child = X/12
Age spent as a teenager = X/7
Age spent between adulthood and marriage = X/6
Age of daughter = X – (X/12 + X/7 + X/6 + 3 + 6) = X - 33X/84 – 9 = 51X/84 – 9
Now, 2(51X/84 – 9) = X
Or 18X/84 = 18
Or X = 84.
Age of daughter = X/2 = 42 years
