Atoms consist of protons, neutrons and electrons. If the mass of neutrons and electrons were made half and two times respectively to their actual masses, then the atomic mass of ${ }_{6} \mathrm{C}^{12}$
Will remain approximately the same
Will become approximately two times
Will remain approximately half
Will be reduced by $25 \%$
Solution
No change by doubling the mass of electrons however by reducing the mass of the neutron to half, total atomic mass becomes $6+3$ instead of $6+6$. Thus reduced by $25 \%$.
