<h3>Answer: 71</h3>
==================================
Explanation:
Multiply the values in the second and third columns. Do this row by row.
Row1: 50*55 = 2750
Row2: 75*32 = 2400
Row3: 150*13 = 1950
Add up the products to get 2750+2400+1950 = 7100
Then divide this by the total frequency 55+32+13 = 100 to get 7100/100 = 71
