None of these
Incorrect AnswerExplanation:
- Total Students: There are 60 students in the class.
- Boys and Girls: Let the number of girls be 7x, then the number of boys is 5x.
- Total Girls: Solve 7x + 5x = 60; therefore, x = 5. This means there are 35 girls and 25 boys.
- Girls Liking Rose: 2/7 of the girls like Roses, so (2/7) * 35 = 10 girls.
- Boys Liking Sunflower: 60% of the girls who like Roses equals 0.6 * 10 = 6 boys.
- Girls Liking Sunflower: 2.5 times the boys who like Sunflower; thus, 2.5 * 6 = 15 girls.
- Boys Liking Lotus: Girls who like Sunflower are 150% of boys who like Lotus. Solve (150/100) * B = 15; thus, B = 10.
- Boys Liking Rose: Remaining boys are 25 - 6 - 10 = 9 boys.
- Girls Liking Lotus: Remaining girls are 35 - 10 - 15 = 10 girls.
- Calculation: (Number of boys who like Rose / Number of girls who like Lotus) * 100 = (9/10) * 100 = 90%.
The correct answer is ? 90%.
