Answers
in a university 200 non-Maharashtrians ladies studying science
Step-by-step explanation:
Exactly a fifth of the number of students in a university of strength 20,000 are ladies
Total Students = 20000
Ladies = (1/5)20000 = 4000
=> Gents = 20000 - 4000 = 16000
33 of every 40 students are Maharashtrians
=> Maharashtrians = (33/40) * 20000 = 16500 Maharashtrians
13 out of every 16 gents are Maharashtrians gents,
=> Maharashtrians gents = (13/16) * 16000 = 13000
=> Non - Maharashtrians gents = 16000 - 13000 = 3000
Maharashtrians Ladies = 16500 - 13000 = 3500
Non - Maharashtrians Ladies = 4000 - 3500 = 500
40% of non- Maharashtrians gents and 55% Maharastrians get have offered Arts subjects, = (40/100)*3000 + (55/100)*16500 = 10275
40% of ladies from Maharashtra and equal percentage of non-Maharashtrians ladies have offered Science subjects
= (40/100) * 3500 + (40/100)* 500 = 1600
non- Maharashtrians ladies studying science = (40/100) * 500 = 200
200 non-Maharashtrians ladies studying science
