The pie chart below has the breakup of the number of students form different departments in an engineering college for the year 2012. The proportion of male to female students in each department is 5:4. There are 40 males in Electrical Engineering. What is the difference between the numbers of female students in the Civil department and the female students in the Mechanical department?

The probabilities that a student passes in Mathematics, Physics and Chemistry are m, p, and c respectively. Of these subjects, the student has 75% chance of passing in atleast one, a 50% chance of passing in atleast two and a 40% chance of passing in exactly two. Following relation are drawn in m, p, and p, c.

(I) p + m + c = 27/20
(II) p + m + c = 13/20
(III) ( p) X (m) X (C) = 1/10
