Geotropism is the growth of a plant in response to gravity.

The profit percent is calculated as (Profit / Cost Price) * 100. In this case, the profit is the difference between the selling price of 80 articles and the cost price of 120 articles. Since the cost price of 120 articles equals the selling price of 80 articles, this means there is a profit equivalent to the cost price of 40 articles (120 - 80). Therefore, the profit percentage is (40/120)*100 = 33.33%.

Michael Faraday was the scientist who invented the electric dynamo in 1831, making electricity practical for technological applications.

The code assigns each letter a number based on its position in the alphabet (A = 1, B = 2, etc.). For example, 'R' is the 18th letter, so it is coded as 18. The coding is further modified by alternating addition and subtraction of 7. In this case, adding 7 to the original positions gives the code. So, 'S' (19th letter) becomes 26, 'T' (20th letter ) becomes 27, and so on. Therefore, 'STATION' is coded as 25-26-7-26-15-21-20.

The expenditure on Fuel and Transport in 2012 is Rs. 225 and the expenditure on Salary is Rs. 538. So, expenditure on Fuel and Transport as a percentage of expenditure on Salary is (225/538 *100) = 41.8%.

Let's say the cost of a pencil is 'x', a pen is 'y', and an eraser is 'z'. We get two equations: 2x + 4y + 8z = 12 and 8y + 10x + 4z = 36. We need to find the value of 3x + 3y + 3z. To do this, we can simplify the equations by dividing the first equation by 2 and the second equation by 4. This gives us: x + 2y + 4z = 6 and 2y + 2.5x + z = 9. We can then multiply the first equation by 3 to obtain 3x + 6y + 12z = 18. We need to find the value of 3x + 3y + 3z, which is half of 3x + 6y + 12z. Therefore, the cost of 3 pencils, 3 pens, and 3 erasers is Rs. 18 / 2 = Rs. 9. However, this is not an option in the provided choices. There seems to be an error in the problem statement or the answer choices. Please verify the original problem.

BUILDING is coded by shifting each letter 3 places back in the alphabet. So, 'B' becomes 'Y', 'U' becomes 'F', 'I' becomes 'R', 'L' becomes 'O', 'D' becomes 'W', 'I' becomes 'R', 'N' becomes 'M', and 'G' becomes 'T'. Therefore, BUILDING is coded as YFROWRMT.
