Question : Which of the following has the highest penetrating power?
Option 1: Alpha ray
Option 2: Beta ray
Option 3: Gamma ray
Option 4: Delta ray
Correct Answer: Gamma ray
Solution : The correct answer is Gamma ray.
Radioactive nuclei emit three types of radiation: alpha, beta, and gamma rays. Alpha rays have the highest ionising power but the least penetrating power. Gamma rays are photons emitted by radioactive nuclei and have the lowest ionising power,
Question : Proportional taxes would help to reduce the autonomous expenditure multiplier because ________.
Option 1: taxes increase the MPC
Option 2: MPC does not have any role in it
Option 3: taxes and MPC become equal
Option 4: taxes reduce the MPC
Correct Answer: taxes reduce the MPC
Solution : The correct option is taxes to reduce the MPC.
Proportional taxes can help reduce the autonomous expenditure multiplier because they have a direct impact on disposable income. The autonomous expenditure multiplier is a concept in economics that represents the change in
Question : Directions: Select the option that is related to the fourth term in the same way as the first term is related to the second term and the fifth term is related to the sixth term. 7 : 40 :: ? : 667 :: 39 : 1512
Option 1: 34
Option 2: 25
Option 3: 47
Option 4: 26
Correct Answer: 26
Solution : Given: 7: 40:: ?: 667:: 39: 1512
Subtract 9 from the square of the first term to get the second number – Like in, 7 : 40→72 – 9 = 40 And in, 39 : 1512→392 – 9 = 1512 Similarly, follow the
Question : If ${\left(x-\frac{1}{x}\right)=\sqrt{6}}$ and $x > 1$, what is the value of ${\left(x^8-\frac{1}{x^8}\right)}$?
Option 1: $1024 \sqrt{15}$
Option 2: $992 \sqrt{15}$
Option 3: $998 \sqrt{15}$
Option 4: $1012 \sqrt{15}$
Correct Answer: $992 \sqrt{15}$
Solution : $(x-\frac{1}{x})=\sqrt{6}$ Squaring both sides, ⇒ $(x^{2} +\frac{1}{x^2}-2)=6$ ⇒ $(x^{2} +\frac{1}{x^2})=8$ Squaring both sides, ⇒ $(x^{4}+\frac{1}{x^4}+2)=64$ ⇒ $(x^{4}+\frac{1}{x^4}) = 62$ Squaring both sides, ⇒ $(x^{8}+\frac{1}{x^8}+2)=3844$ ⇒ $(x^{8}+\frac{1}{x^8})=3842$ ⇒ $(x^{8}+\frac{1}{x^8})^2=3842^2$ ⇒ $(x^{8}-\frac{1}{x^8})^2=(x^{8}+\frac{1}{x^8})^2 - 4$ ⇒ $(x^{8}-\frac{1}{x^8})^2=3842^2 - 2^2$ ⇒ $(x^{8}-\frac{1}{x^8})^2=(3842 +2)(3842-2)$ ⇒ $(x^{8}-\frac{1}{x^8})^2=3844 \times 3840$ ⇒
Question : Nitrogenous food is
Option 1: Carbohydrate
Option 2: lipid
Option 3: Protein
Option 4: Salts
Correct Answer: Protein
Solution : The correct option is Protein
Proteins are large, complex molecules composed of amino acids, which contain nitrogen atoms. This is why proteins are referred to as "nitrogenous compounds." When protein-rich food is consumed, the body breaks down the protein into its constituent amino acids, which
Question : Directions: In the following question, a series is given with one term missing. Choose the correct alternative from the given ones that will complete the series. EFGH, IJKL, MNOP, QRST, ?
Option 1: QRTS
Option 2: VLMN
Option 3: UVWX
Option 4: JIKH
Correct Answer: UVWX
Solution : Given: EFGH, IJKL, MNOP, QRST, ?
Add 4 to the place value of each letter of the previous term to obtain the next term of the series – EFGH→E + 4 = I; F + 4 = J; G + 4 = K; H +
Question : Directions: Which number will replace the question mark (?) in the following series? 5, 12, 26, ?, 110, 222
Option 1: 52
Option 2: 56
Option 3: 54
Option 4: 50
Correct Answer: 54
Solution : Given: 5, 12, 26, ?, 110, 222
Multiply the number by 2 and then add 2 to the resultant, to get the required missing number in the series. 5 × 2 + 2 = 12; 12 × 2 + 2 = 26; 26 × 2

Question : Comprehension:
Read the following passage and answer the questions given after it.
Wetlands are amongst the most productive ecosystems on the Earth and provide many important services to human society. They exhibit enormous diversity according to their genesis, geographical location, water regime and chemistry, dominant species, and soil and sediment characteristics. Globally, the area extent of wetland ecosystems ranges from 917 million hectares (m ha) to more than 1275 m ha. One of the first widely used wetland classification systems, devised by Cowardin et al., 1979, categorised wetlands into marine (coastal wetlands), estuarine (including deltas, tidal marshes, and mangrove swamps), lacustrine (lakes), riverine (along rivers and streams), and palustrine ( marshes, swamps and bogs) based on their hydrological, ecological and geological characteristics.The
The Ramsar Convention on Wetlands was an international treaty signed in 1971. Overall, 1052 sites in Europe; 289 sites in Asia; 359 sites in Africa; 175 sites in South America; 211 sites in North America; and 79 sites in the Oceania region have been identified as Ramsar sites or wetlands of International importance. As per the Ramsar Convention definition most of the natural water bodies (such as rivers, lakes, coastal lagoons, mangroves, peat land, coral reefs) and man-made wetlands (such as ponds, farm ponds, irrigated fields, sacred groves, salt pans, reservoirs, gravel pits, sewage farms and canals) in India constitute the wetland ecosystem distributed in different geographical regions ranging from Himalayas to Deccan plateau. As of February 2022, India has 49 Ramsar sites covering an area of 10,93,636 hectares, the highest in South Asia. As per the estimates, India has about 757.06 thousand wetlands with a total wetland area of 15.3 m ha, accounting for nearly 4.7% of the total geographical area of the country. Out of this, areas under inland wetlands account for 69%, coastal wetlands 27%, and other wetlands (smaller than 2.25 ha) 4%. Gujarat has the highest proportion (17.5%) and Mizoram has the lowest proportion (0.66%) of the area under wetlands. Among Union Territories, Lakshadweep has the highest proportion (around 96%) and Chandigarh has the lowest proportion (3%) of the geographical area under wetlands.
