Correct Answer: 300

Solution : We know, $M_1D_1= M_2D_2,$
Where, $M_1$ and $M_2$ are men and $D1$ and $D_2$ are days.
450 men can finish the construction of an apartment in 20 days.
Here, $M_1=450, D_1=20,$ and $D_2=30$
So, $450×20=M_2×30$
$\therefore M_2=300$
Hence, the correct answer is 300.

Correct Answer: 24 cm

Solution :

As BOC is a right-angled triangle at C,
Applying Pythagoras theorem,
⇒ $(BO)^2 = (CO)^2 + (BC)^2$
⇒ $(20)^2 = (16)^2 + (BC)^2$
⇒ $400 = 256 + BC^2$
⇒ $BC = \sqrt{\text{400 – 256}}$
⇒ $BC = \sqrt{144}$
⇒ $BC = 12$
$\therefore
