e = no. of engineering students, m = no. of MBA students and c = no. of CA students
4e + 3m + 5c = 3650, therefore e = (3650-3m-5c)/4 --------(1)
3c = 2m , therefore c = 2m/3
3e = 2c replacing e with (1) we get,
3(3650- 3m - 5c)/4 = 2c.....replacing c with 2m/3 and solving this equation we get m = 450
So the number of MBA students is 450

No of engg=e
Mba=m
Ca=c
4e+3m+5c=3650
3c=2m m=3c/2
3e=2c e=2c/3
put the value in equestionl
4*2c/3+3*3c/2+5c=3650
c=300
m=3c/2
m=450

1350 = mba
4 e+3 m+ 5 c=3650, 3c=2m , 3e=2c
8c/3 +9c/2 +c =3650, c=300
3m= 9c/2=1350

e = no. of engineering students, m = no. of MBA students and c = no. of CA students
4e + 3m + 5c = 3650, therefore 3m=3650-5c-4e-----------1
3c = 2m , therefore c = 2m/3
3e = 2c ,threrfore e=2(2m/3)/3
subtitute c and e values and slove eqa 1 you will get 730
ans :730
