Question

If M, gm of a substance with specific gravity Si
is mixed with M2 gm of a substance with
specific gravity S, and then the substances are
used to make an alloy. What will be the
specific gravity of the alloy ?
(1) (Mi + M2)/S1S2
(2) (M, + M2)/(M2/S2 + M2/S2)
(3) (M/S + M2/S2)/(M2+ M2)
(4) (M/S) + (M/S2)/(M1M2)
