Answer»

Answer:

Let ρ

and ρ

be the densities of TWO LIQUIDS.

when equal volume of two liquids are mixed , then specific GRAVITY (ρ) is GIVEN by ρ =

(ρ

+ρ

)

and when equal masses of two liquids are added ,then specific gravity (ρ) = 2( ρ 1 +ρ 2ρ 1ρ

2 )so we have

2ρ 1+ρ 2= 4 ....................(1)

and 2( ρ1+ρ 2ρ 1×ρ

2 ) = 3 ..........(2)

on solving 1st and 2ND we get ρ

1=6 and ρ 2 =2
