Question

65 percent of 80 students are good in maths. how many of them are not in this subject? Answer fast!

Answer 1

Answer:

depends on how much you score in every subject. For ex: Suppose you have 5 subjects and If you score 65 marks in every subject then the total marks scored by you will be 65*5 that is 325 and the total marks is 80*5 that is 400.So, the percent scored will be 325÷400*100 i.e 81.25%. Similarly you count for every subject in particular by taking 8 marks as 10%.

Answer 2

Step-by-step explanation:

Total no. of students= 80

Percentage of students who are good in math = 65%

So, percentage of students who are not good in maths

= (100-65)%

= 35%

No. of students who are not good in math= 35% of 80

= (35/100×80)

= 28
