Correct Answer: self-demagnetisation

Solution : The correct option is self-demagnetisation.

Magnets are shielded against self-demagnetisation by magnetic keepers. A permanent magnet's internal magnetic domains may become disorganised when subjected to an external magnetic field that is strong enough and moving in the opposite direction. This will lower the magnet's

Correct Answer: $\frac{n-\sqrt{n^2-m^2}}{m}$

Solution : Given that $\cos 48^{\circ}=\frac{m}{n}$,
We know that $\sec 48^{\circ}=\frac{n}{m}$,
We know that $\tan \theta=\sqrt{\sec^2 \theta-1}$,
Now, $\cot 42^{\circ}=\tan 48^{\circ}=\sqrt{\sec^2 48^{\circ}-1}=\sqrt{\left(\frac{n}{m}\right)^2-1}=\sqrt{\frac{n^2}{m^2}-1}=\frac{\sqrt{n^2-m^2}}{m}$
So, $\sec 48^{\circ}-\cot 42^{\circ}=\frac{n}{m}-\frac{\sqrt{n^2-m^2}}{m}=\frac{n-\sqrt{n^2-m^2}}{m}$.
Hence, the correct answer is $\frac{n-\sqrt{n^2-m^2}}{m}$.

Correct Answer: INR 140 crores

Solution : Production by company A = 90° 
Production by company E = 36°
Total production by A and E together = 90° + 36° = 126°
So, Total cost required = $\frac{126°}{360°}$ × 8,00,000 × 5,000 = 1,400,000,000 or INR 140 crores
Hence, the

Correct Answer: 2

Solution : Given:
DEEPAK is written as 3, and MEME is written as 2.

The number of letters of DEEPAK are divided by 2, to obtain the code –
The number of letters in DEEPAK = 6→6 ÷ 2 = 3
Thus, DEEPAK is coded as 3.
