In B.Com, there are 60% girls and in B.Sc. C.Sci, there are 40% boys. The total number of girls who took admission in B.Sc C.Sci and B.Com courses is what percentage of the total students admitted to the university?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 27%.
Percentage of students in B.Com = 20%
Number of students in B.Com = 20/100 × 7000 = 1400
Number of girls = 1400 × 60/100 = 840
Percentage of students in B.Sc C.Sci = 25%
Number of students in B.Sc C.Sci = 25/100 × 7000 = 1750
Number of boys = 1750 × 40/100 = 700
So, Number of girls = 1750 - 700 = 1050
Now,
The total number of girls in B.Com and B.Sc C.Sci = 840 + 1050 = 1890
Now,
Required percentage = 1890/7000 × 100
⇒ 189/7 = 27%
