(C) Let the rainfall on Wednesday be $x \, cm$.Since it rained as much on Wednesday as on all the other $6$ days combined,the total rainfall for the other $6$ days is also $x \, cm$.Total rainfall for the week $= x + x = 2x \, cm$.The average rainfall for the week is given as $3 \, cm$.Since there are $7$ days in a week,the total rainfall $= 3 	imes 7 = 21 \, cm$.Equating the two expressions for total rainfall: $2x = 21$.Therefore,$x = 21 / 2 = 10.5 \, cm$.Thus,it rained $10.5 \, cm$ on Wednesday.

It rained as much on Wednesday as on all the other days of the week combined. If the average rainfall for the whole week was $3 \, cm$,then how much did it rain on Wednesday? (in $cm$)
