Given : In an examination, a student must get 40% marks to pas-s.If a student gets 36 marks out of 150
To find : Expressing his marks in percentage and more marks needed to pas-s the exam.
Solution :
We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the percentage of his obtained marks and
more marks needed to pas-s the exam)
Now, his marks expressed in percentage will be :
= 100 × (His obtained marks / Total marks of the exam)
= 100 × (36/150)
= 24%
Now, pas-sing marks :
= Total marks of the exam × 40%
= 150 × 40%
= 150 × (40/100)
= 60
Necessary more marks to pas-s the exam :
= Pas-sing marks - Marks obtained by him
= 60 - 36
= 24
Hence, he got 24% marks and he needs 24 more marks to pas-s the exam.
