Since we are working with percentages, the total for both subjects must equal 100%100\%, meaning all sections of the Venn diagram should sum up to 100%100\%.

60x+x+68x=100\therefore 60-x+x+68-x=100

128x=100\Rightarrow 128-x=100

x=28\Rightarrow x=28

Hence 2828 is the minimum percentage of students that passed in both the subjects.
