Q.  The ratio of the number of boys and girls is 3:2 if 20 % of the boys and 30 % of the girls are scholarship holders then the percentage of students who do not get scholarship is_________?

a. 50
b. 72
c. 75
d. 76


ANSWER: See Answer
 
Let the number of boys be 3x and number of girls be 2x.

Number of scholarship holders

= (20/100 ×3x+ 30/100 ×2x) = 6x/5

Number of those who do not hold scholarship

= (5x- 6x/5) = 19x/5

Required percentage = (19x/5 × 1/5x ×100) % = 76 %
