282359 A convex lens \(A\) of focal length \(20 \mathrm{~cm}\) and a concave lens \(B\) of focal length \(5 \mathrm{~cm}\) are kept along the same axis with a distance \(d\) between them. If a parallel beam of light falling on \(A\) leaves the lens \(B\) as a parallel beam then the distance \(d\) is
