**Slot -1 – Quantitative Aptitude – Geometry – Mensuration – Let ABCD be a rectangle inscribed in a circle**

**Let ABCD be a rectangle inscribed in a circle of radius 13 cm. Which one of the following pairs can represent, in cm, the possible length and breadth of ABCD?**

a) 25, 10

b) 24, 12

c) 25, 9

d) 24, 10

**Answer: d) 24, 10**
