joyce and her father are 48 and 20 years younger than her grandfather.if the product of ages of joyce and her father is 480,find the equation which represents their age

(g-48)(g-20) = 480

g = 60

So, the grandfather is 60.

...

Let's break down the information given to solve the problem.

Let's assume that the age of Joyce's grandfather is represented by G. Then, according to the given information:

Joyce's age = G - 48
Her father's age = G - 20

The product of Joyce's age and her father's age is 480. So, we can create an equation to represent this:

(Joyce's age) * (Father's age) = 480

Substituting the values we have:

(G - 48) * (G - 20) = 480

Now, we can simplify and solve this equation to find the value of G.
