A cricketer's average score for 6 innings is 12 runs.
What must he score in his next innings to make his average 13?
If his average score over 7 runs was going to stay at 12 - he would need to score 12 (obviously)To bump the average up to 13 he would have to score an 'extra' for every run completed ie. 7 - so he would have to score an extra 7 runs. 12 + 7 = 19
