An electronic scale; in each measurement, weighs the weight placed on it $\%20$ probability 1 kilogram more than the actual weight, $\%30$ probability 1 kilogram less than the actual weight, and $\%50$ probability correctly. Ali and Mehmet, whose actual weights are 80 and 81 kilograms respectively, will each be weighed once on this scale. Accordingly, what is the probability that Ali and Mehmet's weights will be equal as a result of the measurement, as a percentage? A) 40 B) 35 C) 30 D) 25 E) 20
