Explanation

To find the ages, solve the equations:  

Let the ages be x and 12 - x.

The product is x(12 - x) = 32.

Solving x^2 - 12x + 32 = 0 gives x = 4 and x = 8

So, the ages are 4 and 8 years.

The elder child is: 8 years.

Explanation

The mean is calculated by dividing the sum of the terms by the number of terms.

Mean=Sum of the terms/Number of terms​

Given that the mean is 40 and there are 7 terms, we can find the sum as:

40=The sum of the terms/7​

Multiplying both sides by 7:

$$\text{Sum of the terms}=40\times 7=280$$
