The result of a school is as follows:
1st division 7%, 2nd division 15%, 3rd division 50%. If 98 students were failed then find the total number of students appeared from the school.

• let total no of student is x.
  x-(7 % of x)-(15 % of x) -(50 % of x)=98
  x=350 ans

• students passed = 72 %
  students failed = 100-72= 28% of total students = 98
  total students = 98*100/28 = 350

• total students=x=> passed=x-98;
  then,(7/100+15/100=50/100)*x= x-98;
  x=350.

• 350
  (7x/100)+(15/100)+(50x/100)+98=x
  x=9800/28
  x=350
