Khalid is now four times as okd as his daughter. Ten years ago,if the sum of their ages was sixty. Find the present age of his daughter?
khalid=k
daughter=d
first statement
k=4d...(1)
second statement
(k-10)+(d-10)=60.
k+d=60+20
k+d=80...(2)
plug 1 into 2 and there you go
Well, if Khalid is now four times as "okd" as his daughter, I'm assuming you mean "old," right? So, let's call the daughter's age x. That means Khalid's age is 4x.
Now, if we go back in time ten years, we can subtract 10 from both their ages. So, the daughter's age would be x - 10, and Khalid's age would be 4x - 10.
According to your statement, the sum of their ages ten years ago was sixty. So, we can set up an equation:
(x - 10) + (4x - 10) = 60
Simplifying that equation, we get:
5x - 20 = 60
Adding 20 to both sides:
5x = 80
Dividing both sides by 5:
x = 16
So, the present age of Khalid's daughter is 16.
Let's assume the present age of Khalid's daughter is "x" years.
According to the given information:
Khalid is now four times as old as his daughter, which means Khalid's age = 4 * (daughter's age).
Ten years ago, if the sum of their ages was sixty:
(Khalid's age 10 years ago) + (Daughter's age 10 years ago) = 60
Since the present age of a person is equal to their age 10 years ago plus 10 years, we can rewrite the equation as follows:
(Khalid's present age - 10) + (Daughter's present age - 10) = 60
Substituting Khalid's age (4 * x) and Daughter's age (x) into the equation:
(4 * x - 10) + (x - 10) = 60
Simplifying the equation:
5x - 20 = 60
Adding 20 to both sides of the equation:
5x = 80
Dividing both sides of the equation by 5:
x = 16
Therefore, the present age of Khalid's daughter is 16 years.
To find the present age of Khalid's daughter, let's assign variables to represent their ages:
Let "x" represent the daughter's present age.
Since Khalid is four times as old as his daughter, Khalid's present age would be 4x.
According to the information given, ten years ago, the sum of their ages was sixty. So, we need to subtract ten years from their current ages and set it equal to sixty:
(x - 10) + (4x - 10) = 60
To solve this equation, let's combine like terms:
5x - 20 = 60
Next, isolate the variable by adding 20 to both sides of the equation:
5x = 80
Now, divide both sides of the equation by 5 to solve for "x":
x = 16
Therefore, Khalid's daughter is currently 16 years old.
