To solve average problems using the ratio method, calculate the difference between the overall average and each group's average, then use these differences to find the ratio of group sizes. For example, with an overall average of 35, passed candidates average of 39, and failed candidates average of 15, the differences are 4 (39-35) and 20 (35-15), giving a ratio of 1:5. This means for every 1 failed candidate, there are 5 passed candidates. With 120 total candidates, dividing into 6 parts (1+5) gives 20 failed candidates and 100 passed candidates.

Average Problem in Seconds| Ratio Method #quantitativeaptitude #fastcalculation @SowndhQuants追加:
35 Other past candidates order Average mark of 39 failed candidates order average mark 15.
The ratio method is all fun long.
Overall count of 21 20 Kamala. Under 120 to come average 35 other base is all fun long.
So 39 past or a park on in one of 15.
Failed 15. So 39 minus 35 put in a room.
4 gallon in the same as one 35 minus 15 and 20 in the render correlation with you now.
5 is to one word.
Total hour but other than the other part of the 120 people.
120 members The five parts done past.
So in a word.
five by six and other five plus one hour What the more parts are coming?
into 120 The solve fun long.
20 equal to 100 So 100 members done. past or coming You mean in 20 failed.
