Answer 1

Answer:

65

Step-by-step explanation:

NOTE :

Average = Sun of scores in all matches/ No. if matches

SOLUTION :

Total sun of 24 match score will be average of 24 matches multipled with 24

Lets consider the average runs before 25th match be ' x ' Hence, the average of 25th match will be x+1.4. Therefore

x + 1.4 = (x*24)+100

25

25 (x + 1.4) = 24x+100

25x + 35 = 24x + 100

25x - 24x = 100 - 35

x = 65

The average runs before 25th match be 65
