Correct Answer: 12 cm

Solution : Given: Two circles of radii 3 cm and 8 cm, the distance between the centres = 13 cm and PQ is the direct common tangent.
We know,
The length of the direct common tangent of two circles = $\sqrt{d^2-(r_1-r_2)^2}$
Here, the distance between the

Correct Answer: 8 km/hr

Solution : Time taken to cover a distance of 12 km = 78 minutes
Two-thirds of the 12 km was covered at = 10 km/hr
Time = $\frac{\text{Distance}}{\text{Speed}}$
Two thirds of $12$ km = $12\times{\frac{2}{3}}$ = 8 km
Speed for 8 km distance cover = 10

Correct Answer: 15 cm

Solution : $\triangle$ABC ~ $\triangle$PQR
Perimeter($\triangle$ABC) = 36 cm
Perimeter($\triangle$PQR) = 24 cm
PQ = 10 cm
$\frac{AB}{PQ}$ = $\frac{\text{Perimeter($\triangle$ABC)}}{\text{Perimeter($\triangle$PQR)}}$
⇒ $\frac{AB}{10}$ = $\frac{36}{24}$
⇒ AB = $\frac{360}{24}$ = 15 cm
Hence, the correct answer is 15 cm.
