A heavy nucleus having mass number 200 gets disintegrated into two small fragments of mass numbers 80 and 120. If binding energy per nucleon for parent atom is $6.5 \mathrm{MeV}$ and for daughter nuclii is $7 \mathrm{MeV}$ and $8 \mathrm{MeV}$ respectively, then the energy released in the decay will be
  1. 1. $200 \mathrm{MeV}$
  2. $120 \mathrm{MeV}$
  3. $220 \mathrm{MeV}$
  4. $180 \mathrm{MeV}$
