Answer 1

Let the total score in first five matches be x
And the Total score in last eight matches be y
A. To. Q
(x+y)/13=42
x+y=446-------------(1)
x/5=54
x=270
Put x=270in eq(1)
y=446-270
=176
So average score in last eight matches
176/8
=22

Answer 2

Answer:

The average score in his last eight matches is 22.

Step-by-step explanation:

Given : Average score of a cricketer in 13 matches is 42 runs. if the average score in the first five matches be 54 runs.

To find : What is the average score in his last eight matches?

Solution :

Let the total score in first five matches be x

And the total score in last eight matches be y

According to question,

$\frac{x+y}{13}=42$

(x+y)/13=42

$x+y=446$   ------------[1]

and $\frac{x}{5}=54$

$x=270$

Put x=270 in equation [1]

$270+y=446$

$y=176$

So average score in last eight matches

$\frac{176}{8}=22$

Therefore, The average score in his last eight matches is 22.
