Question : Comprehension:
Read the given passage carefully and answer the questions that follow. Mountains occupy about a quarter of the Earth’s land, harbour most of its biodiversity hotspots, and supply fresh water to an estimated half of humanity. Present on every continent, mountains include a multitude of ecosystems holding many unique species, such as snow leopards and mountain gorillas. They are also home to great cultural diversity among people who have adapted to the challenges of mountain life. Their special traditions and breath-taking scenery attract ever-growing numbers of tourists. Mountain regions are particularly sensitive to degradation from both human pressures and climate change. Steep slopes mean the clearing of forest for farming, settlements, or infrastructure, which can cause serious soil erosion as well as the loss of habitat. Erosion and pollution harm the quality of the water flowing downstream. Climate change threatens the quantity and timing of water supplies to farms, cities, industry and power stations. Fast-rising temperatures are forcing mountain species, ecosystems and the people that depend on them to adapt or migrate.

Question : Directions: A set of letters is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. G can be represented by 04, 11, 42, etc. and P can be represented by 68, 75, 99, etc. Similarly, you have to identify the set for the word given below.

Question : The value of $\frac{(243)^\frac{n}{5}\times 3^{2n+1}}{9^{n}\times 3^{n-1}}$ is:
Option 1: 3
Option 2: 9
Option 3: 6
Option 4: 12
Correct Answer: 9
Solution : Given: $\frac{(243)^\frac{n}{5}\times 3^{2n+1}}{9^{n}\times 3^{n-1}}$ = $\frac{(3^5)^\frac{n}{5}\times 3^{2n+1}}{3^{2n}\times 3^{n-1}}$ = $\frac{3^n\times 3^{2n+1}}{3^{2n}\times 3^{n-1}}$ = $\frac{3^{3n+1}}{3^{3n-1}}$ = $\frac{3^{3n}×3^1}{3^{3n}×3^{-1}}$ = ${3^{2}}$ = $9$ Hence, the correct answer is 9.
