A) 50
B) 72
C) 75
D) 76
Correct Answer: D
Solution :
Let the number of boys = 3x and that of girls = 2x |
Number of boys who do not hold scholarship = 80% of 3x |
\[=3x\times \frac{80}{100}=\frac{12x}{5}\] |
Number of girls who do not hold scholarship |
\[=2x\times \frac{70}{100}=\frac{14x}{10}\] |
\[\therefore \] Number of students who do not hold scholarship |
\[=\frac{12x}{5}+\frac{14x}{10}=\frac{24x+14x}{10}=\frac{38x}{10}\] |
\[\therefore \] Required percentage |
\[=\frac{\frac{38x}{10}}{5x}\times 100=\frac{38}{10\times 5}\times 100=76%\] |
