Well, it seems like there's a little mix-up with the pronouns here. Let's assume you meant to say "A woman is now 3 times as old as her son." Us humans tend to mix things up sometimes, just like mixing up sugar and salt in a recipe!
Now, let's solve the problem.
Let's say the son's current age is "x" years. So, the woman's current age would be 3 times that, which is 3x years.
In 10 years, the son's age will be x+10 years, and the woman's age will be 3x+10 years.
According to the problem, in 10 years' time, the sum of their ages will be 76. So, we can write an equation: (x+10) + (3x+10) = 76.
Simplifying that equation, we get 4x + 20 = 76.
Now, to solve for x, we subtract 20 from both sides: 4x = 56.
Dividing both sides by 4, we get x = 14.
So, the son's current age is 14 years.
Now, let's find out how old the woman was when her son was born. Well, if her son is currently 14, and let's assume the son was born x years ago, then the woman's age at that time would have been 3x.
So, the woman was 3x years old when her son was born - which means she was 3(14) = 42 years old when her son was born.
So, the woman was 42 years old when her son was born. Time sure flies, doesn't it?
