Correct Answer: 21 cm

Solution : Let the radius of the first circle be $r_1$.
Circumference of the first circle $=2\pi r{_1}$
⇒ $308 = 2×\frac{22}{7}×r{_1}$
⇒ $r_1$ = 49 cm
Let the radius of the 2nd circle be $r_2$.
Circumference of the 2nd circle $=2\pi r{_2}$
⇒ $440 =

Correct Answer: $-\frac{4}{15}$

Solution : $x\sin ^{2}60^{\circ}-\frac{3}{2}\sec 60^{\circ}\tan^{2}30^{\circ}+\frac{4}{5}\sin^{2}45^{\circ}\tan ^{2}60^{\circ}=0$
$⇒x(\frac{\sqrt3}{2})^2-\frac{3}{2}×2×(\frac{1}{\sqrt3})^2+\frac{4}{5} ×\frac{1}{2}×(\sqrt{3})^2=0$
$⇒\frac{3x}{4}-1+\frac{6}{5}=0$
$⇒\frac{3x}{4}=-\frac{1}{5}$
$⇒x=-\frac{4}{15}$
Hence, the correct answer is $-\frac{4}{15}$.

Correct Answer: $29 \frac{13}{18}$

Solution : Distance travelled by Shatabdi in 5 hours($T_1$), $D_1$ = 700 km
Distance travelled by Shatabdi in 11 hours($T_2$), $D_2$ = 1012 km
​​Average Speed
= $\frac{D_{1}+D_{2}}{T_{1}+ T_{2}}$
= $\frac {700+1012}{(5+11)}$
= $107$ km/hr
= $107\times \frac{5}{18}$ m/s
= $29\frac{13}{18}$ m/s
Hence, the correct answer
