When asked a question about age 17, Galixia replied "in three years y age will equal to the sum of my birthday year"
what year did it take place
answer chhoices
a.1970
b.2000
c.1993
d/1990
Ps. Heres the answer (D) Explain please
To find the answer, we need to use some basic arithmetic.
Let's assume that the current year is "y". According to Galixia's statement, in three years her age will be equal to the sum of her birthday year. This means that in three years, her age will be "y + 3", and her birthday year will be "y".
So, we can set up the equation:
y + 3 = y
Next, we can solve for "y" by subtracting "y" from both sides of the equation:
3 = 0
This is not a true statement, which means that our assumption was incorrect. Therefore, we need to try a different approach.
Since Galixia's age is 17 in the current year, we can subtract 17 from the currently unknown year, "y", to find her birth year.
y - 17 = y
Simplifying the equation:
-17 = 0
Again, this is not a true statement, so our assumption is incorrect.
Let's try another approach: since Galixia's age in three years will be equal to her birthday year, we can set up the equation:
y + 3 = y
Simplifying the equation:
3 = 0
Once again, this is not a true statement.
From these observations, we can conclude that Galixia's statement is not logically possible. The answer choices provided (a. 1970, b. 2000, c. 1993, d. 1990) are irrelevant to this question.
