Let No. of people $= x$
$125$ people can finish a work in $120$ days.
Hence
$\frac{1 2 5 \times 1 2 0}{1} = \frac{1 1 \times x}{1}$
$x = \frac{1 2 5 \times 1 2 0}{1 0 0} \Rightarrow x = 25 \times 6$
$x = 150$
No. of people $= 150$

$\frac{3 a + 5 b}{3 a - 5 b} = 5 \Rightarrow 3 a + 5 b = 5 (3 a - 5 b)$
$\Rightarrow 3 a + 5 b = 15 a - 25 b \Rightarrow 12 a = 30 b$
$\Rightarrow \frac{a}{b} = \frac{3 0}{1 2} = \frac{5}{2} \Rightarrow a : b = 5 : 2$

Let No. of people =x 125 people can finish a work in 120 days.Hence1125×120​=111×x​x=100125×120​⇒x=25×6x=150No. of people =150
