The question asks to identify the chemical used for making germ-free drinking water. This process is known as disinfection, and it involves using a chemical agent to kill or inactivate harmful microorganisms.
Correct Option: A) CaOClβ (Calcium hypochlorite or bleaching powder) is a powerful oxidizing agent and is widely used as a disinfectant for water purification. It releases hypochlorous acid, which kills bacteria and other microorganisms.
Study the given diagram carefully and answer the question that follows.

The question asks for the solid product formed when ferrous sulphate is heated. This involves understanding the thermal decomposition reaction of ferrous sulphate.
Correct Option: B) Ferric oxide
The question asks to identify the correct statement regarding phloem, a plant tissue responsible for transport. We need to evaluate each option based on the known characteristics and functions of phloem.
A) Phloem carries photosynthetic products from leaves to other plant parts. This statement accurately describes the primary function of phloem, which is the translocation of sugars (produced during photosynthesis in leaves) to various parts of the plant where they are needed for growth, storage, or metabolism.
To solve this problem, we need to compare the positions of digits in the original number with their positions after arranging the digits in ascending order. We will list the original number and the rearranged number, then count how many digits have changed their position.
| Position | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th | 9th |
|---|---|---|---|---|---|---|---|---|---|
| Digit | 3 | 5 | 4 | 6 | 9 | 8 | 3 | 2 | 9 |
| Position | 1st | 2nd | 3rd | 4th | 5th | 6th | 7th | 8th | 9th |
|---|---|---|---|---|---|---|---|---|---|
| Digit | 2 | 3 | 3 | 4 | 5 | 6 | 8 | 9 | 9 |
| Position | Original Digit | New Digit | Changed? |
|---|---|---|---|
| 1st | 3 | 2 | Yes |
| 2nd | 5 | 3 | Yes |
| 3rd | 4 | 3 | Yes |
| 4th | 6 | 4 | Yes |
| 5th | 9 | 5 | Yes |
| 6th | 8 | 6 | Yes |
| 7th | 3 | 8 | Yes |
| 8th | 2 | 9 | Yes |
| 9th | 9 | 9 | No |
Correct Option: D) 8
The position of 8 digits will change as compared to that in the original number.
The problem is a coding-decoding question. We need to identify the pattern used to transform the given words and then apply the same pattern to the target word.
D) ENVRE is the correct answer because it follows the established pattern of swapping the first two letters, keeping the middle letter, and swapping the last two letters.
This problem can be solved by applying Ohm's Law, which relates voltage (EMF), current, and resistance in an electrical circuit. Given the resistance and the induced current, we can directly calculate the induced EMF.
The current is given in milliamperes (mA), which needs to be converted to amperes (A).
\[ 1 \, \text{mA} = 1 \times 10^{-3} \, \text{A} \]So, \(I = 1 \times 10^{-3} \, \text{A}\).
Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, provided the resistance (R) remains constant. It is expressed as:
\[ V = I \times R \]In this case, the induced EMF (electromotive force) is equivalent to the voltage (V).
Substitute the values of current and resistance into Ohm's Law:
\[ \text{EMF} = (1 \times 10^{-3} \, \text{A}) \times (4 \, \Omega) \] \[ \text{EMF} = 4 \times 10^{-3} \, \text{V} \]Since \(10^{-3} \, \text{V}\) is equal to 1 millivolt (mV), we can write:
\[ \text{EMF} = 4 \, \text{mV} \]Correct Option: C) 4 mV
This is a circular seating arrangement problem. We need to deduce the positions of the five people around a circular table based on the given clues and then identify the person who is an immediate neighbour of both A and F.
From clue 1, we have D - A - E.
From clue 2, E is next to F and K. Since E is already next to A, the other neighbour of E must be F. So, the sequence becomes D - A - E - F.
Now, F is next to E and K. We have E - F. So, the other neighbour of F must be K. The sequence extends to D - A - E - F - K.
Since it's a circular table with five people, the person at the end of this sequence (K) must be next to the person at the beginning (D) to complete the circle. So, the final arrangement is D - A - E - F - K - D (circularly).
Looking at our arrangement (D - A - E - F - K), the person sitting between A and F is E.
A) E is the immediate neighbour of both A and F, as derived from the seating arrangement.
