Question : ABC is an isosceles triangle having AB = AC and $\angle$A = 40$^\circ$. Bisector PO and OQ of the exterior angle $\angle$ ABD and $\angle$ ACE formed by producing BC on both sides, meet at O, then the value of $\angle$BOC is:
Option 1: 70$^\circ$
Option 2: 110$^\circ$
Option 3: 80$^\circ$
Option 4: 55$^\circ$
Correct Answer: 70$^\circ$
Solution : Given, an isosceles $\triangle$ ABC with AB = BC And, $\angle$ A = 40$^\circ$ with bisectors PO and OQ of $\angle$ ABD and $\angle$ ACE. In $\triangle$ ABC, $\angle$A + $\angle$ B+ $\angle$ C = 180$^\circ$ Or, 40$^\circ$ + 2$\angle$C = 180$^\circ$ Or, $\angle$ B
Question : A is faster than B. A and B each walk 24 km. The sum of their speeds is 7 km/hr and the sum of their time taken is 14 hours. Then A's speed is equal to:
Option 1: 3 km/hr
Option 2: 4 km/hr
Option 3: 5 km/hr
Option 4: 7 km/hr
Correct Answer: 4 km/hr
Solution : Let the speed of A = $x$ km/hr and the speed of B = $(7-x)$ km/hr So, the time taken by A and B to walk 24 km are ($\frac{24}{x}$) hours and ($\frac{24}{7 - x}$) hours, respectively. Now $(\frac{24}{x}) + (\frac{24}{7-x}) =14$ $⇒ 24(7-x)+24x
