Let sets **A** and **B** have **$$5$$** elements each. Let mean of the elements in sets **A** and **B** be **$$5$$** and **$$8$$** respectively and the variance of the elements in sets **A** and **B** be **$$12$$** and **$$20$$** respectively. A new set **C** of **$$10$$** elements is formed by subtracting **$$3$$** from each element of **A** and adding **$$2$$** to each element of **B**. Then the sum of the mean and variance of the elements of **C** is:
