Question : In a circle with centre O, AB is a diameter and CD is a chord which is equal to the radius OC. AC and BD are extended in such a way that they intersect each other at a point P, exterior to the circle. The measure of $\angle$APB is:
Option 1: 30°
Option 2: 45°
Option 3: 60°
Option 4: 90°
Correct Answer: 60°
Solution : In the triangle, OCD is an equilateral triangle as OC = OD = CD (which are all radii of the circle). Therefore, $\angle$COD = 60°. $\angle$CBD = $\frac{1}{2}\angle$COD = 30° Since AB is a diameter, $\angle$ACB = 90° (angle in a semi-circle) In triangle BCP,
Question : Two pipes A and B can fill a cistern in $12 \frac{1}{2}$ hours and 25 hours, respectively. The pipes were opened simultaneously, and it was found that, due to leakage in the bottom, it took one hour 40 minutes more to fill the cistern. If the cistern is full, in how much time (in hours) will the leak alone empty 70% of the cistern?
Option 1: 40
Option 2: 35
Option 3: 30
Option 4: 50
Correct Answer: 35
Solution : LCM of 12.5 and 25 = 25 Capacity of the cistern = 25 units Efficiency of A = $\frac{25}{12.5}$ = 2 units/hour Efficiency of B = $\frac{25}{25}$ = 1 unit/hour Combined efficiency of A and B = 2 + 1 = 3 units/hour Time taken
