- lets average for 9 innings=x
then
(9*x +50)/10=x+4
9x+50=10x+40
x=10
so 9 innings average = 9*10
10 innings=90+50/10
=14 - 9 years agoHelpfull: Yes(1) No(0)
- average for 9th innings be x;
score in 10th match=10*(x+4)-9*x;
=>50=10x+40-9x;
=>x=10;
option b is correct - 9 years agoHelpfull: Yes(1) No(0)
- C.14
9 ININ 10 =========== 90 RUNS
10 ININ 14 =========== 140 RUNS
DIFFERENCE = 50 IN 10 TH INNINGS
SO NEW AVERAGE = 14 - 9 years agoHelpfull: Yes(0) No(0)
