<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
