Explanation / Answer

mass of neutron m = 1.008665 u

Mass of U 235 is m ' = 235.0439299 u

Mass of 80 Ge is M = 79.92537 u

Mass of 154 Nd is M ' = 153.92948 u

Mass defect dm = ( m+ m') -( M+ M ' + 2m)

                        = m ' - M - M ' - m

                        = 0.1804149 u

We know 1 u = 931.5 MeV

So, energy released E = dm x 931.5 MeV

                                = 0.1804149 x931.5 MeV

                                = 168.056 MeV
