✅ Correct Answer: C. 24 = 2.12 + 0

📚 Explanation: The division algorithm states that a number can be written as (Divisor multiplied by Quotient) plus Remainder. In this case, 24 is being divided by 2.

Since 2 multiplied by 12 is exactly 24, the remainder is 0. Option C perfectly follows the mathematical rule for a perfect division of the number 24.

✅ Correct Answer: C. 11

📚 Explanation: The number of saplings actually planted is 127 - 6 = 121. For the garden to have as many rows as saplings in each row, the number must be a perfect square.

The square root of 121 is 11. Therefore, there are exactly 11 rows in the garden, with 11 saplings in each row.

✅ Correct Answer: A. 7

📚 Explanation: Let the three numbers be x, y, and z. In continued proportion, y squared equals x multiplied by z. The total product is x * y * z = 343.

Substituting xz with y squared, we get y multiplied by y squared = y cubed = 343. The cube root of 343 is 7, so the median proportional is 7.

✅ Correct Answer: B. 55, 143

📚 Explanation: To find the actual numbers from their ratio and greatest common divisor (GCD), we simply multiply each part of the ratio by the GCD. The GCD is given as 11.

Calculation: 5 * 11 = 55 and 13 * 11 = 143. Thus, the two numbers are 55 and 143, which share a common factor of 11.

✅ Correct Answer: A. Anemometer

📚 Explanation: An anemometer is a scientific instrument used for measuring the speed and direction of the wind. it is a common tool in weather stations to monitor the atmosphere.

The most common type has several cups that spin as the wind blows past them. This device is different from a barometer, which measures air pressure.

✅ Correct Answer: B. Rs. 45 and Rs. 55

📚 Explanation: The total parts are 9 + 11 = 20. To find the value of one part, we divide 100 by 20, which equals 5.

Therefore, A receives 9 * 5 = Rs. 45 and B receives 11 * 5 = Rs. 55. This is a basic proportional division problem often found in competitive mathematics.
