Question

There are 'b' bricks that need to stacked after k' of them in terms 'b'and 'k', what percent of the bricks have not yet been stacked

Answer 1

100([b-k]/b) percent of the bricks have not yet been stacked

It is given that the total number of bricks that are needed to be stacked = b.

Number of bricks which have been stacked = k.

So, the number of bricks that havent been stacked is equal to (Total bricks - number of stacked bricks)

= (b - k)

To represent the percentage of bricks which are unstacked.

It is equal to [(Unstacked bricks / Total bricks) × 100]%

= [ (b-k)/b × 100]%

= 100([b-k]/b) %
