Correct Answer: 40,000

Solution : Investment ratio of P and Q = 150000 : 450000 = 1 : 3
Since investment time is the same for both the person.
So, Profit ratio of P and Q = 1 : 3
Now,
(1 + 3) units = 200000
$\therefore$ 1 unit

Correct Answer: $150\left (3 +{\sqrt3} \right)$

Solution :
In $\Delta ABC$
$\tan 60^{\circ} = \frac{AB}{BC}$
$⇒\sqrt{3} = \frac{AB}{BC}$
$⇒AB = \sqrt{3} BC \quad \text{-----------------------(1)}$
In $\Delta ABD$
$\tan 45^{\circ} = \frac{AB}{BD}$
$\Rightarrow 1 = \frac{AB}{BD}$
$⇒AB = BD \quad \text{---------------------------------(2)}$
From equation $(1)$ and equation $(2)$
$\Rightarrow BD = \sqrt{3}

Correct Answer: 10

Solution : Given: 10 men can do a work in 25 days. After 12 days of work, 3 more men were engaged to finish the work.
Here, $M_1=10,M_2=10+3=13,D_1=25-12=13$
We know, $M_1D_1= M_2D_2$
⇒ 10 × 13 = 13 × D₂
$\therefore$ D₂ = 10 days
