Question : If $a+b+c+d=4$, then find the value of $\frac{1}{(1-a)(1-b)(1-c)}+\frac{1}{(1-b)(1-c)(1-d)}+\frac{1}{(1-c)(1-d)(1-a)}+\frac{1}{(1-d)(1-a)(1-b)}$?
Option 1: 0
Option 2: 5
Option 3: 1
Option 4: 4
Correct Answer: 0
Solution : Given: $a+b+c+d=4$ $\frac{1}{(1-a)(1-b)(1-c)}+\frac{1}{(1-b)(1-c)(1-d)}+\frac{1}{(1-c)(1-d)(1-a)}+\frac{1}{(1-d)(1-a)(1-b)}$ = $\frac{1-d+1-a+1-b+1-c}{(1-a)(1-b)(1-c)(1-d)}$ = $\frac{4-(a+b+c+d)}{(1-a)(1-b)(1-c)(1-d)}$ = $\frac{4-4}{(1-a)(1-b)(1-c)(1-d)}$ = $\frac{0}{(1-a)(1-b)(1-c)(1-d)}$ = $0$ Hence, the correct answer is 0.

Question : In $\triangle ABC, \angle B = 60^\circ$ and $\angle C = 40^\circ$, AD and AE are respectively the bisectors of $\angle A$ and perpendicular on BC. Find the measure of $\angle EAD$.
Option 1: $11^\circ$
Option 2: $10^\circ$
Option 3: $12^\circ$
Option 4: $9^\circ$
Correct Answer: $10^\circ$
Solution : Given: In $\triangle ABC$, $\angle B = 60^\circ$ and $\angle C = 40^\circ$. We know that, $\angle BAC+\angle ABC+\angle ACB=180^\circ$ ⇒ $\angle BAC = 180^\circ-60^\circ-40^\circ$ ⇒ $\angle BAC = 80^\circ$ Since AD is the angle bisector of $\angle BAC$ in $\triangle ABC$ $\therefore \angle BAD
