\mathrm{mass\: of \: \mathrm{AgCl}=0.4}
\mathrm{moles \: of \: \mathrm{AgCl}=\frac{0.4}{143.5}= moles\: of \: \: \mathrm{Cl}}
\mathrm{\therefore \: mass\: of\: Cl=\frac{0.4}{143.5} \times 35.5}
\begin{aligned} \therefore \quad \text { %by mass of Cl} &=\frac{0.4 \times 35.5}{143.5 \times 0.25} \times 100 \\ &=39.58 \% \end{aligned}

Hence,the answer is 40 when rounded off to the nearest integer
