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 : 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.

Question : The following table shows the number of sweets manufactured by six factories.
What is the respective ratio of sweets manufactured by factories P, Q, and R together in the year 1998, to the sweets manufactured by factories S, T, and U together in the same year?
Option 1: 568 : 499
Option 2: 61 : 72
Option 3: 61 : 42
Option 4: 40 : 51
Correct Answer: 568 : 499
Solution : Using the information given in the table: Sweet manufactured by factories P, Q, and R in 1998 = 178 + 240 + 150 = 568 Sweet manufactured by factories S, T, and U in 1998 = 130 + 177 + 192 = 499

Question : The hour hand moves through 4 hours and has a length of 6 cm. Find the area (in cm2, rounded off to two decimal places) of the sector covered by the hour hand.
Option 1: 32.69
Option 2: 30.67
Option 3: 37.71
Option 4: 35.75
Correct Answer: 37.71
Solution : In 4 hours, the hour hand covers = $0.5° \times 4 \times 60 = 120°$ Now, the area of the sector covered by the hour hand = $\pi \times 6^2\times \frac{120°}{360°}$ ⇒ Area = $12\pi = 37.71\ \mathrm{cm^2}$ Hence, the correct answer is 37.71.
