Question : Directions: Select the option that is related to the third letter cluster in the same way as the second letter cluster is related to the first letter cluster. PORCH : IDSPQ :: MOIST : ?
Option 1: UTJQO
Option 2: OMITS
Option 3: OPJTU
Option 4: UTJPN
Correct Answer: UTJPN
Solution : Given: PORCH : IDSPQ :: MOIST : ?
Follow the pattern to obtain the required code –
Thus, PORCH is coded as IDSPQ. Similarly, follow the same pattern for MOIST –
Thus, MOIST is coded as UTJPN. Hence, the fourth option is correct.
Question : If $\sqrt{0.04\times 0.4\times a}=0.004\times 0.4\times \sqrt{b},$ then the value of $\frac{a}{b}$ is:
Option 1: $16\times 10^{-3}$
Option 2: $16\times 10^{-4}$
Option 3: $16\times 10^{-5}$
Option 4: $16 \times 10^{-6}$
Correct Answer: $16\times 10^{-5}$
Solution : $\sqrt{0.04\times 0.4\times a}=0.004\times 0.4\times \sqrt{b}$ Squaring both sides, we get, $⇒0.04\times 0.4\times a=0.004^2\times 0.4^2\times {b}$ $⇒\frac{a}{b} = \frac{0.004 \times 0.004 \times 0.4 \times \times0.4}{0.04 \times 0.4}$ $⇒\frac{a}{b} = \frac{16}{10^{5}}$ $\therefore$ $\frac{a}{b} = 16 \times 10^{-5}$ Hence, the correct answer is $16 \times 10^{-5}$.
Question : Directions: In the question, a part of the sentence is in bold. Below are given alternatives to the bold part at (1), (2), and (3) that may improve the sentence. Choose the correct alternative. In case no improvement is needed, your answer is (4).

In the original sentence, just before a week is not the correct way to express the time frame. A week ago is the appropriate way to indicate a past time point.
Therefore, the correct sentence is, "I
Question : Which of the following principles is used to produce 'low temperatures'?
Option 1: Superconductivity
Option 2: Joule-Kelvin effect
Option 3: Thermo-electric effect
Option 4: Adiabatic demagnetisation
Correct Answer: Adiabatic demagnetisation
Solution : The correct option is Adiabatic demagnetisation.
To achieve low temperatures, an adiabatic demagnetisation method is helpful. This technique helps to achieve low temperatures of around 1K for the electronic paramagnetic salts. However, the temperature can be as low as possible for the nuclear

Question : What is the length of a bacterial cell?
Option 1: 3 to 5 µm
Option 2: 1 to 40 µm
Option 3: 30 to 50 µm
Option 4: 0 to 3 µm
Correct Answer: 3 to 5 µm
Solution : The correct option is 3 to 5 µm.
The average length of bacterial cells falls within the range of 3 to 5 micrometres (µm). This range is a generalisation, and the actual size can vary depending on the bacterial species. Some
