Rohit is the brother of Kala. Kala is the wife of Dilip.

Therefore, Dililp is brother-in-law of Rohit.

Hence, option A is the correct answer.

Option D is correct.

Let the price be Rs.10

And the quantity is 10.

Then, the expenses will be Rs.100

Now the price is decreased by 25%

So,

25% of Original Price = 

Decreased price = (10 – 2.5) = 7.5

And the quantity is increased by 30%

So,

30% of the original quantity = 

Increased quantity = (10 + 3) = 13

New expenses = 7.5 × 13 = 97.5

Decrease in expense = 97.5 – 100 = –2.5

Required percentage =

For insulators, on increasing temperature the conductivity also increases.

● When the temperature is increased, the atoms of the material vibrate and it makes the valence electrons present in the valence band to shift to the conduction band. This leads to increase in conductivity of an element.

● When the conductivity of the material increases, it means that the resistivity decreases and so the current flow increases.
