it is better and safer to use (!list) than (list==NULL) as while implementation there might be some memory - segmentation fault errors.

Now, 

Let 60 % of mangoes weigh X grams and,

      40 % of mangoes weigh Y grams 

Let total number of mangoes be "n".

 

A/Q

\(350 = {X \over 0.6n}\)  ⇒  \(350*0.6 = {X \over n}\)   ⇒  \(210 = {X \over n}\)     ------------------------- (1)

\(400 = {Y \over 0.4n}\)   ⇒ \(400*0.4 = {Y \over n}\)   ⇒   \(160 = {Y \over n}\)     --------------------------(2)

(1) + (2)

\(210 + 160 = { X + Y \over n}\)

⇒ \(370 = {Total Wt. \over n}\)

Therefore, Average Weight of mangoes = 370 grams

X.(Y−Z) can be drawn as follows:
 <dot>  =
Similarly, (X.Y)−(X.Z) can be drawn like this:
<minus> =

Hence, we can say that X.(Y−Z) = (X.Y)−(X.Z)
