Well if you are asking what will be the observation then here is the answer buddy....

First the raisins will swell up(Endosmosis)due to water(Hypotonic solution) being absorbed.. Then the raisin would shrink to small size(Exosmosis) due to water coming out of it when placed in salt or sugar solution(Hypertonic solution)

Hope this helps you buddy
