To find the mean score of the girls, we will first calculate the total score of all students and the total score of the boys. Then, we will subtract the boys' total score from the overall total score to get the girls' total score. Finally, we will divide the girls' total score by the number of girls to find their mean score.
Correct Option: B) 17

Vishnu spends ₹5,000 in buying 12 tables and some chairs. The cost of one table is ₹50 and that of one chair is ₹40. What is the ratio of the number of chairs to the number of tables purchased?
The problem requires us to find the ratio of the number of chairs to the number of tables purchased. We are given the total amount spent, the number of tables, the cost of one table, and the cost of one chair. We will first calculate the total cost of the tables, then subtract this from the total amount spent to find the amount spent on chairs. From the amount spent on chairs and the cost per chair, we can determine the number of chairs. Finally, we will form the required ratio.
D) 55 : 6 is the correct ratio of the number of chairs to the number of tables purchased.

The question asks to identify the plant tissue characterized by living, elongated cells with irregular thickenings at the corners. This description points to a specific type of simple permanent tissue.
A) Collenchyma — Collenchyma cells are indeed living, elongated, and characterized by unevenly thickened cell walls, particularly at the corners, due to the deposition of cellulose, hemicellulose, and pectin. They provide flexible support to growing parts of the plant.
To find the Least Common Multiple (LCM) of two numbers, we can use the prime factorization method. This involves finding the prime factors of each number, then taking the highest power of all common and uncommon prime factors.
Correct Option: D) \(6 \times 8 \times 9\)
This product evaluates to \(48 \times 9 = 432\), which is the LCM of 48 and 54.
The question asks to identify which option is NOT a pollinating agent for cross-pollination. Pollinating agents are external factors that transfer pollen from the anther of one flower to the stigma of another flower (cross-pollination). We need to evaluate each option based on its role in facilitating pollen transfer.
D) Plants. Plants are the entities that undergo pollination, either as pollen donors or pollen recipients. They do not act as external agents to transfer pollen from one flower to another. Wind, water, and animals are all external factors that facilitate this transfer.
