Answer:
Required Answer:-
We have:
The ratio of the present ages of a mother and her
daughter is 7 : 1
Four years ago, the ratio of their ages was 19 : 1.
To FinD:
What will be the mother's age four years from now?
Step-by-Step Explanation:
Let the ages of mother and daughter be x and y respectively.
According to condition -(1)
➛ x : y = 7 : 1
By the principle of proportion, Product of means = Product of extremes.
➛ x = 7y --------(1)
According to condition -(2)
➛ x - 4 : y - 4 = 19 : 1
Again by the principle of proportion, Product of means = Product of extremes.
➛ x - 4 = 19(y - 4)
➛ x - 4 = 19y - 76
➛ x - 19y = -72 ------(2)
Substituting x = 7y in equation (2),
➛ 7y - 19y = -72
➛ -12y = -72
➛ y = 6
Then, x = 42
Therefore:-
The age of the mother after 4 years will be 42 + 4 = \boxed{\bf{46 \:years}}
46years
Those diagnosed in stage 4 who decide against treatment live an average of 6 months. Researchers use tumor grading to estimate how fast a tumor may grow. Cell abnormalities and how rapidly the cancer cells are dividing play a role in overall tumor growth. These factors are associated with survival.
