DIRECTIONS for questions 13 and 14:
The batting average (BA) of a test batsman is computed from runs scored and innings played-completed innings and incomplete innings (not out) in the following manner:
r1 = number of runs scored in completed innings
n1 = number of completed innings
r2 = number of runs scored in incomplete innings
n2= number of incomplete innings
BA = (r1 + r2)/ n1
To better assess a batsman's accomplishments, the ICC is considering two other measures MBA1 and MBA2 defined as follows:
MBA1 = r1 / n1 + n2 / n1 + max [0, (r2 / n2 - r1 / n1)]
MBA2 = (r1 + r2 )/ (n1 + n2 )
