Solution

The correct option is B 12
Given that 16 workers take 48 hours to build the wall. If the time is reduced to 32 hours, then let the number of workers required be y.
$16 \times 48 =$ $y \times 32$
$y = 24$
Now, if 4 workers left, the remaining number of workers at the site is $16 - 4 = 12$
Thus, additional number of workers required will be
$24 - 12 = 12$
