gain percent  =   (selling price - cost price )/cost price  * 100

            = (5.58 - 4.35)/4.35 * 100  = 28.27 %

profit needed = 171

let number of books be = n

profit = n * (selling price - buying price) = 171

              n = 171/1.23 = 139  approx.

gain %:     171/(139 * 4.35)  * 100  = 28.28 %
