Q. A certain quantity of rice is spent daily for 30 students in a hostel. One day some students were absent as a result, the quantity of rice has been spent in the ratio of 6 : 5. How many students were present on that day?
Option
(a)24
(b)20
(c)15
(d)25

• given that total students are 30,
  lets take absent students are x , so 30-x are the present students
  30/30-x=6/5 =====> x=5, 30-x=30-5==> 25
  so ans:- d
• 10 years agoHelpfull: Yes(23) No(0)
• 30/x = 6/5
  then x=25
  so ans is 'd''25'
• 10 years agoHelpfull: Yes(9) No(0)
• let us take absent students be x
  w.k.t total students = 30
  so number of present students = 30-x
  from the qstn 30/(30-x) = 6/5
  ==> x= 5
  so 30-5= 25 students were present on that day.
  ans is d(25)

• given total students=30
  let absent students=X
  so students present on that day=30-x
  given when there where 30 students quantity of rice spent=6
  and for 30-x students quantity of rice spent =5
  30-x=5 ,x=30-5 =>x=25.
• 10 years agoHelpfull: Yes(2) No(0)
• 30/x=6/5
  then x=25
  so ans (d) is correct.

• simply assume absent students=x then,
  30/x=6:5
  =25(ans)
  
• 10 years agoHelpfull: Yes(1) No(0)
• 30/30-x=6/5
  6x=30
  x=5
  30-x=30-5=25
• 6 years agoHelpfull: Yes(1) No(0)
• let y no of student were absent
  then
  30:30-y::6:5
  solving this we get y=5 so...30-5=25 ans

• Just check options......
  Only option D is giving the ratio of 5:6 w.r.t 30
• 8 years agoHelpfull: Yes(0) No(0)
• 6/5=30/x
  x=25
• 6 years agoHelpfull: Yes(0) No(0)
• 30/30-x=5/6=>x=5
  30-x=>25
• 5 years agoHelpfull: Yes(0) No(0)
• 30/30-x=6/5
  i.e x = 5
  so 30-5=25
• 4 years agoHelpfull: Yes(0) No(0)
• given that total student are 30
  30/30-x=65
• 4 years agoHelpfull: Yes(0) No(0)
• let us take absent students be x
  Given that the total no.of students are=30
  30/x=6/5
  150/x=6
  150/6=x
  so,x=25
  Ans:-"d"
• 4 years agoHelpfull: Yes(0) No(0)
• The answer is 25
• 3 years agoHelpfull: Yes(0) No(0)
• it is option d
  lets assume absent students as x
  so
  30-x are present
  30/30-x=6/5
  6x=30
  x=5
  30-5= 25
