Dear preetam,
here we assume that the required Luminious flux of source be P Watt.
we know that for 1 Watt of 555nm luminious flux is 685. so for P watt, luminious flux is 685P.
thier ratio is equal to relative luminousity and is given by 0.6
from here we get luminious flux in terms of P which is equal to 120*685 because question is asking for 120 W. from there we have calculated P.

dear,
charge is electric polarity of the body it may be postitve or negative.
mass is quantity to measure matter enclosed inside a particular body of certain volume.
mass is always constant. but charge may differ w .r.t. other charges present around it.

relation between mass and charges is only that there can be no charge on a mass less body. ..
there is no formula to relate them. . .
