Hi pclawong,

If we assume the intake for the first year to be x.
Since there is a increase of 20%(1/5th) of the intake in the inception year, the constant increase is .2x
Therefore, the intake for the second year is 1.2x.
Similarly the intake for the third year is 1.4x, for the fourth year is 1.6x, and for the fifth year is 1.8x

Now, we know that S = x+1.2x+1.4x+1.6x+1.8x = 7x

So at the end of the fifth year, only 4 year students remain having 6x students.

Hence the fraction is $$\frac{6S}{7}$$(Option B)

Please find the video explanation provided by Experts Global
