Directions: Refer the following data to answer the questions given below.

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. (r1 + r2 ) BA = n1 To better assess a batsman’s accomplishments, the ICC is considering two other measures MBA1 and MBA2 defined as follows: MBA1 = r1 + n2 + max [0, (r2 ? r1) ] n1 n1 n2 n1 (r1 + r2 ) MBA2 = (n1 + n2 ) Based on the information provided which of the following is true?

Visual question. Notice that the difference between BA and MBA is in the denominator. Since the denominator in MBA2 is higher, it implies that this quantity must be smaller. But MBA1 could be greater than MBA2 but less than BA. Hence statement (d) is correct.

Total of (x – 1) numbers =17   

This means x – 1 = 17 and x = 18.

Hence x = 612. Number erased = 10.
