- Let total student x
0.2x+(2/3)*96+96=x
x=200 ans - 10 years agoHelpfull: Yes(24) No(0)
- 96+64=0.8x
so x=200
- 10 years agoHelpfull: Yes(4) No(0)
- options are a)72 b)100 c)150 d)200
- 10 years agoHelpfull: Yes(2) No(0)
- total number of students in the schooolare 200
- 10 years agoHelpfull: Yes(2) No(2)
- let total students=x
no.of students less than 8 years old=20/100*x=1/5*x
no.of student greater than 8 years old=96*(2/3)=64
no.of students which are 8 years old=96
1/5*x+64+96=x
x=200
total students=200 - 7 years agoHelpfull: Yes(1) No(0)
- 80%= 96+2/3(96)=160
100%=200 - 10 years agoHelpfull: Yes(0) No(1)
- the ans 200
- 10 years agoHelpfull: Yes(0) No(1)
- assume total students x
0.2x+(2/3)*96+96=x
160=0.8x
x=200 - 10 years agoHelpfull: Yes(0) No(0)
- Let the number of students be x. Then,
Number of students above 8 years of age = (100 - 20)% of x = 80% of x.
=> 80% of x = 48 + 2/3 of 48.
=> (80/100) x = 80.
=> x = 100. - 8 years agoHelpfull: Yes(0) No(2)
