Answer 2

108

Explanation:

$fraction \: of \: rotten \: eggs = \frac{2}{12}$

$fraction \: of \: broken \: eggs = \frac{1}{12}$

$fraction \: of \: bad \: eggs = \frac{2}{ 12 } + \frac{1}{12} \\ = \frac{3}{12}$

$\frac{3}{12} = \frac{1}{4}$

$total \: no. \: of \: bad \: eggs \: = 144 \times \frac{1}{4} \\ = \frac{144 \times 1}{4}eggs \\ = \frac{144}{4}eggs \\ = 36 \: eggs$

$total \: no. \: of \: useful \: eggs = 144 - 36 \\ \: \: \: \:\: \: \: \:\: \: \:\: \: \: \:= 108 \: eggs$

Therefore, total number of eggs that can be used is 108.
