(B) 20
(C) 30
(D) 25​

Answer 1

Answer:

15

Step-by-step explanation:

Club A had won 30% of the first 60 matches

=> Matches won = (30/100) * 60 = 18 Matches

Let say Club A play  A matches & wins  All

then Total Matches Played = 60 + A

Total Win = 18 + A

44% of ( 60 + A) = 18 + A

=> (44/100) (60 + A) = 18 + A

=> (11/25)(60 + A) = 18 + A

=> 660 + 11A = 450 + 25A

=> 14A = 210

=> A = 15

15 number of additional minimum matches the Club A should play to achieve a success rate of 44% in that season
