To find the mean, we need to multiply the frequency of each value by the value itself, then add up these products and divide by the total frequency. Using this formula, we get:

(10*15 + 8*20 + 13*25 + 9*30 + 6*35 + 4*40)/50 = 782/50 = 15.64

Therefore, the correct choice is A) 31.14, which is twice the mean.
