At present, the age of Aliya is x–10 years. What will be her age after 13 years where the value of x is 25 years?
A. 15 years
B. 20 years
C. 25 years
D. 28 years
Explanation:
The given statement states that the present age of Aliya is x–10 years, where the value of x is 25 years. So, substituting the value of x in the expression, we get;
Aliya’s present age = 25–10 = 15 years.
After 13 years, her age will be 15 + 13 = 28 years.
Analyzing Aliya’s Age: A Mathematical Perspective
Understanding the Given Information
The given information states that the present age of Aliya is x–10 years, with the value of x being 25 years. This means that Aliya’s present age can be calculated by subtracting 10 from x. Substituting the value of x=25, we find that Aliya’s present age is 25–10 = 15 years.
Determining Aliya’s Age after 13 Years
To calculate Aliya’s age after 13 years, we need to add 13 to her present age. Aliya’s present age is 15 years, so adding 13 years to it gives us: 15 + 13 = 28 years. Therefore, Aliya’s age after 13 years will be 28 years.
Mathematical Representation:
Aliya’s present age = x – 10
Given x = 25
Aliya’s present age = 25 – 10 = 15 years
Aliya’s age after 13 years = Aliya’s present age + 13 = 15 + 13 = 28 years
Implications of Mathematical Calculation
The mathematical calculation confirms that Aliya’s age after 13 years will be 28 years. It’s important to understand and apply mathematical operations correctly to solve such problems and arrive at an accurate age.
