The correct answer is Option 1 i.e. 13.75 days.

M₁ × D₁ × H₁ = M₂ × D₂ × H₂

where, M = number of workers , D = Days and H = hours

⇒ 10 × 22 = 16 × D₂

⇒ D₂ = 13.75 days

The correct answer is option 4 i.e. None of the conclusions follows.

The following figure can be formed from the statements.

Conclusions:

I. Some cats are tigers: False (It is possible but not definite).

II. Some horses are cats: False (It is possible but not definite).

III. Some dogs are tigers: False (It is possible but not definite).

Hence, the correct answer is None of the conclusions follows

The correct answer is Option 3 i.e. 13824

A pair of squares and a cube are given.

(18)² = 324

(20)³ = 8000

Similarly,

(22)² = 484

(24)3 = 13824

Hence, the correct answer is 13824

The correct answer is option 2 i.e. 9

The logic used here is:

1st column: (12 × 15) × 7 = 1260 ÷ 6 = 210

2nd column: (14 × 18) × 6 = 1512 ÷ 6 = 252

Similarly, 3rd column: (26 × 13) × ? = (338 × ?) ÷ 6 = 507

= (338 × ?) = 3042

= ? = 3042 ÷ 338

= 9

The correct answer is option 4 i.e. Lieutenant Governor.

• Lieutenant Governor is the administrative head of the Union Territories of Andaman and Nicobar Islands, Delhi, and Puducherry. In other union territories, administrators are appointed.
• Governor is the head of the state appointed by the President.
• The Lieutenant Governor is also appointed by the President for a term of five years.

The correct answer is Option 3 i.e. Shape selective catalysis.

The type of catalytic reaction that relies on the pore structure of the catalyst and the size of the reactant and product molecules is referred to as "shape-selective catalysis." In shape-selective catalysis, the catalyst has specific pore sizes and shapes that allow only molecules of certain sizes and shapes to enter and react within the pores. This property enables selective catalysis based on molecular dimensions, influencing reaction pathways and product distributions, which is particularly important in refining processes and the synthesis of complex molecules.

The correct answer is Option 3 i.e. Its acceleration remains constant.

This is because, in free fall, the only force acting on the object is gravity, which imparts a constant acceleration towards the Earth. This acceleration, denoted as g, is approximately 9.8 m/s² near the Earth's surface. The velocity of the object increases continuously in the direction of the gravitational force, but the rate of this increase, or acceleration, remains constant.

The correct answer is option 4 i.e. Amylase.

Amylase enzyme is found in all members of the animal kingdom except protozoa. This enzyme catalyzes the hydrolysis of starch into sugars and is present in the saliva of humans and some other mammals, where it initiates the chemical process of digestion. Protozoa, lacking amylase, are unable to digest starch and fats.

The correct answer is Option 2 i.e. Iron.

Iron absorption is significantly enhanced by the presence of vitamin C in the diet. Vitamin C, or ascorbic acid, promotes the conversion of dietary non-heme iron (found in plant sources) into its ferrous form, which is more readily absorbed by the intestinal lining. Additionally, vitamin C binds to iron, preventing it from forming insoluble compounds that the body cannot absorb. This synergistic effect increases overall iron uptake, helping to prevent iron deficiency anaemia and supporting proper red blood cell function.

The correct answer is option 3 i.e. 95%.

Total funds collected from China = 20%

⇒ 20% = 20/100 × 28550 lakhs = Rs. 5710 lakh

Total funds collected from Germany = 19%

⇒ 19% = 19/100 × 28550 lakhs = Rs. 5424.5 lakh

⇒ Required percentage = 5424.5/5710 ×100 = 54245/571 = 95%
