Problem Analysis

In this problem, we are given that Samir's grandmother is older than 57 years but younger than 65 years. We are also given that the sum of the units digit and the tens digit of her age is equal to 8. We need to determine how old Samir's grandmother is.

Solution

Let's assume the tens digit of Samir's grandmother's age is x and the units digit is y. According to the given information, we have the following equations:

1. x + y = 8 (the sum of the units digit and the tens digit is equal to 8) 2. 57 < 10x + y < 65 (Samir's grandmother is older than 57 years but younger than 65 years)

To solve this problem, we can use trial and error or a systematic approach. Let's try different values for x and y and check if they satisfy both equations.

If we start with x = 5, then y = 3 satisfies both equations: - 10x + y = 10 * 5 + 3 = 53, which is greater than 57 - 10x + y = 10 * 5 + 3 = 53, which is less than 65 Therefore, Samir's grandmother is 53 years old.

Answer

Samir's grandmother is 53 years old.
