Question

Average of 5 innings is 20. if four innings are 32, 10, 40 and 12 find the 5th inning score

Answer 1

Let the fifth inning be x
According to question :
(32+10+40+12+x)/5=20
94+x=20×5
94+x=100
x=100-94
x=6

Answer 2

$Average = \frac{sum of quantities }{No. of quantities}$
___________________________________

Average = $\frac{32+ 10 + 40 + 12+ (5th)}{5}$

20= $\frac{94 +(5th)}{5}$

20 × 5 =94 + (5th)

100 = 94 + (5th)

100 - 94 = (5th)

6 = (5th)


Now,

Score  of 5th inning was 6 


i hope this will help you
