The average stock value of three companies U, V and W is 545 billion. While the average stock value of three companies V, X and Y is 678 billion. Stock value of company V is 477 billion. What is the average stock value of U, V, W, X and Y? Correct Answer 638.4
Given:
Average stock value of 3 companies U, V and W = 545 billion
Average stock value of 3 companies V, X and Y = 678 billion
Stock value of company V = 477 billion
Formula used:
Sum of total stock value = Average × Number of companies
Calculation:
Sum of total stock value of U, V and W = 545 × 3 = 1635 billion
Sum of stock value of U and W = 1635 – 477 = 1158 billion
Sum of total stock value of V, X and Y = 678 × 3 = 2034 billion
Sum of stock value of X and Y = 2034 – 477 = 1557 billion
Total stock value of U, V, W, X and Y = (1158 + 1557 + 477) billion = 3192 billion
Average stock value of U, V, W, X and Y = 3192/5 = 638.4 billion
∴ The average stock value of 5 companies is 638.4 billion
