HCU MCA 2016 Paper

If D=the day (1 – 366) in year Y, then the day of the week for D can be calculated using the following formula d = $\left(\mathit{D}+\mathit{Y}+\frac{\mathit{Y}-1}{4}-\frac{\mathit{Y}-1}{100}+\frac{\mathit{Y}-1}{400}\right)$ mod 7 where d=1 would mean Sunday, 2=Monday and so on. Which of the following days can the first day of a century NOT be ?
