A boy got 224 points out of 300, but he had to score atleast 79%. Now he has one more exam left with him how much he have to score in remaining exam to score atleast 79% if it is of 100 points.

• To score 79% overall,he must get (4*79)=316pts.
  So in the 4th exam he must get (316-224)= 92.

• 92.02 is correct ans
  300*x/100=224 then x=224/3
  79-(224/3=74.66)=4.34
  4.34*300/100=13.02
  79+13.02=92.02

• (224/300)*100 =74.6%. 79-74.6= 4.4 % required. so 44 mars required out of 100..

• (224/300)*100= 74.67%
  so 79-74.67=4.33%
  means more 4.33 required then 79%
  i.e. (79+4.33)=83.33 marks required out of 100 to score atleast 79%..........
