2. 21.6%
3. 19.4%
4. 17.6%
Solution:
1. Ans. 4.
Solution:
number of boys absented in college B= 430+52=482
Number of girls absented in college B= 482-244=238
Total number of students in college B= 430+482+508+238=1658
Option 4 is correct.
2. Ans. 2.
Solution:
let presented girls= 2x so absented girls= x+4
Total number of girls = 1512- 1052 =460
Therefore 2x+x+4=460
X= 152 so absented girls = 156
Absented boys =1052- 650= 402
Difference = 402-156=246
Option 2 is correct.
3. Ans. 1.
Solution:
Number of girls in college C = 1512- 1052+294 =754
Total number of students in college C = 318+ 754=1072
Total number of absented boys and girls= 1072- 230= 842
Option 1 is correct.
4. Ans. 2
Solution:
boy presented in college C=318/2= 159
In college D = 568-165= 403
Average= (650+430+159+403)/4= 410.5
Option 2 is correct.
5. Ans. 4.
Solution- number of girls presented/absented = 328/2= 164
Absent % of girls = 50%
Number of boys presented = 164+20= 184
Present % of boys = 184×100/568=32.39%
% difference = 50- 32.4= 17.6%
So option 4 is correct.
