Answers and Solutions :



1.1

Chemistry = 18*23 = 414
After increasing 26 students = 414+26 =440

Physics = 17*18 = 306
After decreasing 26 students = 306-26=280

percentage = 280*100/440= 63.63~= 64%

2.3


English  = (27*18)-20 =486-20 =466
Physics = 17*18 = 306

Hindi = 8*18 =414
Chemistry = 18*23 = 414
Biology = 12*18 -35= 216-35= 181

Difference = ( English + Physics) - ( Hindi + Chemistry + Biology  )

==> difference = 772-739 = 33



3.1

Students passed in English = 18*27 =486

Students passed in Chemistry =18*23=414

after increasing 69 in Chemistry = 441+69= 510

Ratio between English and Chemistry = 486 : 510 =81:85

4.2

Total together = 1800 ( 13*150/(100*100) + 8*75/(100*100)) 

==> Total together = 351+108 = 459


5. 1

Male students passed in Physics = 7/9 * 1800 * 17/100 = 238
Students passed in Chemistry = 23*1800/100 = 414

percentage = 238/414 *100 = 57.48
