A heavy nucleus having mass number $200$ gets disintegrated into smaller fragments of mass number $80$ and $120$. If binding energy per nucleon for parent atom is $\text{6.5}eV$ and for daughter nuclei are $7eV$ and $8eV$ respectively and the energy released in the decay is given by $X \times {10}^{5}eV$, then $X$ will be
