Question

a batsman in his 11th Ganesh make a score of 68 and thereby increases his average score by 2 what is his average score after the 11th innings​

Answer 1

Correct question be :

  A batsman in his 11th innings make a score of 68 and thereby increases his average score by 2 what is his average score after the 11th innings?

Solution :

Let us take in first 10 innings, his total runs was x

Then , average in 1st 10 innings = x/10

Given that, (x + 68)/11 = (x/10) +2

  ==> (x + 68)/11 = (x + 20)/10

  ==> 10 (x + 68) = 11 (x + 20)

  ==> 10x + 680 = 11x + 220

  ==> 11x - 10x = 680 - 220

  ==> x = 460

Total score in 1st 10 innings = 460

So, his total score after 11th innings

             = 460 + 68 = 528

Average score be

= (460/10) + 2 = 46 + 2 = 48

ANSWER:--

{let the runs be {X}

{So,let the total score after 10 innings = 10x runs.}

{Score in 11th innings = 68 runs.}

{11th innings = 10x+68 runs.}

here,are the following steps follows the solution to this problem

{ 11 innings = (10x+68)/11

={ x+2 .}

{11 × (x+2)= 10x + 68

{x = 46}

{let the Average score of the innings= x+2 = 48 runs}
