- 16
- 18

**Problem 5. **

AB is the diameter of a circle with centre at O. The tangent at C meets AB produced at Q. If $\angle CAB=34^0$, then the value of $\angle CBA$ is,

- $34^0$
- $56^0$
- $124^0$
- $68^0$

**Problem 6.**

Two circles touch each other externally at A. PQ is a direct common tangent to the two circles with P and Q as points of contact. If $\angle APQ=35^0$ then $\angle PQA$ is,

- $75^0$
- $65^0$
- $35^0$
- $55^0$

- $6\sqrt{7}$ cm
- $6\sqrt{2}$ cm
- $6\sqrt{5}$ cm
- $6\sqrt{3}$ cm

- $36^0$
- $28^0$
- $32^0$
- $56^0$

** Problem 10.**

A square is inscribed in a quarter circle in such a manner that two of its adjacent vertices lie on two radii at an equal distance from the centre, while the other two vertices lie on the circular arc. If the square has sides of length $x$, then the radius of the circle is,

- $\displaystyle\frac{\sqrt{5}x}{\sqrt{2}}$
- $\sqrt{2}x$
- $\displaystyle\frac{16x}{\pi + 4}$
