Answer 2

$\huge \mathbb{Question}$

▶A group of soldiers can destroy a bunker in 7 days. However 12 of them fell ill. The remaining can do the job 10 days. Find the original group strength.

$\huge \mathbb{Answer}$

▶$x \: \times 7 = (x - 12) \times 10$

$7x = 10x - 120$

$7x - 10x = - 120$

$- 3x = - 120$

$\boxed{x = 40}$
