Question

A cricketer has completed 20 innings and his average is 44.5 runs. How many runs must be make in next innings 30 as to raise his average to 45

Answer 1

Answer:

460

Step-by-step explanation:

first 20 innings average 44.5 means total runs= 20×44.5=890

again 30 innings average 45 means total runs= 30×45= 1350

so needed runs to reach at 45 average in 30 innings =1350-890=460 answer

Answer 2

Given

Number of innings completed by a cricketer=20

Average runs scored by him in 20 innings =44.5

Average runs score in next 30 innings =45

To find

Runs score by him in 11 innings

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

Average Runs scored by a cricketer in 20 innings=44.5

Average=Total runs ÷ No.of innings

Total runs scored = No.of innings × average

Total runs scored = 20×44.5=890

Let us assume that the cricketer score 'x' in next innings say 30 innings

Then ,our Equation becomes

=>890+x/30 = 45

=>890+x= 45×30

=>890+x=1350

=>x=1350-890

=>x=460

Hence,the cricketer scored 460 runs in his next 30 innings.
