Explanation

Since the student who left weighed 45 kgs, the total weight of all 60 students (including the student who left) is 59x + 45.

When the student left, the average weight of the remaining 59 students increased by 200g (or 0.2 kgs), so we can set up the equation:

59x + 45 = 60(x - 0.2)

Simplifying the equation, we get:

59x + 45 = 60x - 12

Solving for x, we get:

x = 57

So, the correct answer is: 57
