When equal volumes of two substance are mixed, the specific gravity of the mixurie is 4. When equal weights of the same substance are mixed, the specific gravity of the mixture is 3. The soecufuc gravities of the two substance could beA. 6 and 2B. 3and 4C. `2.5` and `3.5`D. 5 and 3 |

Answer» Correct Answer - A `4=(Vd_(1)+Vd_(2))/(2V)` or, `d_(1)+d_(2)=8`…(i) `3=(m+m)/((m//d_(1))+(m//d_(2)))` or` (2 d_(1)d_(2))/(d_(1)+d_(2))=3` …(ii) Solving eqs. (i) and (ii), we get `d_(1)=6` and `d_(2)=2`. |
