Correct Answer:

Solution : Since the rotation of the figure is not allowed, we will check which of the option figures can exactly fit in the given question figure.

From the above, it is clear that the second option figure is embedded in the question figure. Hence, the second option

Correct Answer: 90 km/h

Solution : Speed of train = 80 km/h
Total distance covered by the train = 80 × 4.5 = 360 km
Therefore, the speed required to cover the same distance in 4 hours:
Speed = $\frac{\text{Distance}}{\text{Time}}$
= $\frac{360}{4}$ = 90 km/h
Hence, the correct answer is

Correct Answer: 200 m/sec

Solution :
Height of the aeroplane = BD = CE = $1500\sqrt{3}$ m and $\angle$ BAE = 60°, $\angle$ CAE = 30°
In $\Delta$ ADB,
$\tan 60°=\frac{1500\sqrt{3}}{AD}$
⇒ $\sqrt{3}=\frac{1500\sqrt{3}}{AD}$
⇒ AD = $\frac{1500\sqrt{3}}{\sqrt{3}}$
⇒ AD = 1500 m
In $\Delta$ CAE,
$\tan 30°=\frac{1500\sqrt{3}}{AE}$
⇒ $\frac{1}{\sqrt{3}}=\frac{1500\sqrt{3}}{AE}$
⇒

Correct Answer: 10.8

Solution : LCM of 1.2 and 2.7 = LCM of $\frac{12}{10}$ and $\frac{27}{10}$
We know LCM of fractions = $\frac{\text{LCM of numerators}}{\text{HCF of denominators}}$
Now, HCF of denominators = HCF of 10 and 10 = 10
And LCM of numerators = LCM of 12 and 27 =
