Q5) A batsman has a certain average runs for 11 innings. In the 12th inning he made a score of 90 runs and thereby decreased his average by 5. His average after 12th inning is:

The correct option is B (b) 145Ans. Let the average in 11 innings = x Given (11x+90)/12 = x-5(11x+90) = 12 * (x-5)(11x +90 ) = 12x - 6011x + 90 = 12x - 6060+90 = 12x - 11x Therefore x = 150 x = 150 and hence the average after 12 innings will be 150-5 = 145

The correct option is B (b) 145
Ans.
Let the average in 11 innings = x
Given
(11x+90)/12 = x-5
(11x+90) = 12 * (x-5)
(11x +90 ) = 12x - 60
11x + 90 = 12x - 60
60+90 = 12x - 11x
Therefore x = 150
x = 150 and hence the average after 12 innings will be 150-5 = 145
