A nucleus with mass number $\displaystyle 242$ and binding energy per nucleon as $\displaystyle 7.6$ MeV breaks into two fragment each with mass number 121. If each fragment nucleus has binding energy per nucleon as $\displaystyle 8.1$ MeV , the total gain in binding energy is $\displaystyle \_\_\_\_$ MeV.
Official answer
From NTA’s final answer key for this paper.
121
