Correct Answer: $\sqrt{3}$

Solution : Given: $\tan 240^\circ$
= $\tan (180^\circ+60^\circ)$
= $\tan 60^\circ$
= $\sqrt{3}$
Hence, the correct answer is $\sqrt{3}$.

Correct Answer: $2(ab+bc+ca)$

Solution : By using the identity:
$(a+b+c)^{2} = a^{2}+b^{2}+c^{2}+2(ab+bc+ca)$
$\therefore$ $(a+b+c)^{2}- a^{2}- b^{2}- c^{2} = 2(ab+bc+ca)$.
Hence, the correct answer is $2(ab+bc+ca)$.

Hence, the first option is correct.

Correct Answer: 52 – 61

Solution : Let's check the options –
First option: 52 – 61→61 – 52 = 9 ≠ 11
Second option: 43 – 54→54 – 43 = 11
Third option: 72 – 83→83 – 72 = 11
Fourth option: 18 – 29→29 – 18= 11

Hence,

Correct Answer: 13 cm

Solution :
AB = 24 cm
And OC = 5 cm
We have to find AO.
C is the middle point of the chord.
$\therefore$ AC = $\frac{24}{2} = 12\ \mathrm{cm}$
Using Pythagoras theorem,
$\text{AO}^2 = \text{AC}^2 + \text{OC}^2$
⇒ $\text{AO}^2 = 12^2 + 5^2$
⇒
