The ratio of the number of boys to girls in a school is 5:3. If 20% of the boys and 25% of the girls are scholarship holders, what percent of the total students do not hold a scholarship?
A. 80%
B. 78.125%
C. 78%
D. 82.5%
Answer: Option B
Solution (By JKSSB Mock Tests)
Total = 5k+3k=8k. Scholarship boys=0.2×5k=k, girls=0.25×3k=0.75k, total scholarship=1.75k. Scholarship % = (1.75k/8k)×100 = 21.875%, so without = 78.125%.
