A school has 900 students out of which 60% are boys. What is the ratio...
Ratio of 75% of total girls to 80% of total boys

Given:
Total number of students = 900
Percentage of boys = 60%

Calculations:
Number of boys = 60% of 900 = 0.60 * 900 = 540
Number of girls = Total students - Number of boys = 900 - 540 = 360
75% of total girls = 0.75 * 360 = 270
80% of total boys = 0.80 * 540 = 432

Ratio:
Ratio of 75% of total girls to 80% of total boys = 270 : 432 = 5 : 8
Therefore, the correct answer is option D) 5 : 8.

A school has 900 students out of which 60% are boys. What is the ratio...
Boys = 60%
Girls = 100% – 60% = 40%
So the answer = 75% of 40% : 80% of 60% = 5 : 8
Hence, Option E is correct.
