I bought 27 apples. 29 of them were found rotten. How many were good ones?
To find good apples
Given :- Total apples bought = 27
Rotten apples = 29 of 27 = 29×27=6
Goodapples=Totalapples-Rottenapples=27-6=21
Therefore, good apples are 21
If 16 out of 200 apples were rotten, what per cent of apple is rotten ?
