Direction: Read the following information carefully and answer the following questions.
A class has total 60 students. All the students likes only one of 3 flowers i.e Lotus, Sunflower and Rose. Number of boys is 5/7 times the number of girls. Ratio of number of girls who likes Rose and total number of girls is 2 : 7. Number of boys who likes Sunflower is 60% of the number of girls who likes Rose. Number of girls who likes Sunflower is 2.5 times the number of boys who likes Sunflower. Number of girls who likes Sunflower is 150% of the number of boys who likes Lotus.
Number of boys who likes Rose is what % of the number of girls who likes Lotus?
85%
90%
75%
95%
None of these
- 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%.
