write a situation that you have experience involving percentage



please answer my question​

Sagot :

Mike needs 30% to pass. If he scored 212 marks and falls short by 13 marks, what was the maximum marks he could have got

Solution:

If Mike had scored 13 marks more, he could have scored 30%

Therefore, Mike required 212 + 13 = 225 marks

Let the maximum marks be m.

Then 30 % of m = 225

(30/100) × m = 225

m = (225 × 100)/30

m = 22500/30

m = 750
