Calculation of Natasha's Brothers' Ages

To solve this problem, let's assign variables to the ages of Natasha's brothers. Let's call the age of the older brother "x" and the age of the younger brother "y".

According to the given information, the sum of their ages is 1664, which can be expressed as:

x + y = 1664

It is also stated that the younger brother is half the age of the older brother, which can be expressed as:

y = (1/2) * x

To find the values of x and y, we can solve these two equations simultaneously.

Substituting the value of y from the second equation into the first equation, we get:

x + (1/2) * x = 1664

Simplifying the equation, we have:

(3/2) * x = 1664

To solve for x, we can multiply both sides of the equation by (2/3):

x = (2/3) * 1664

Evaluating the expression, we find:

x = 1109.33

Since we are dealing with ages, we can round the value of x to the nearest whole number:

x ≈ 1109

Now, substituting the value of x back into the second equation, we can find the value of y:

y = (1/2) * 1109

Evaluating the expression, we find:

y = 554.5

Again, rounding the value of y to the nearest whole number:

y ≈ 554

Therefore, Natasha has two brothers.
