S is the standard deviation (for M25 it is 4 as per Table 2) X is the factor based on the grade of concrete (for M25 it is 5.5 as per Table 1) Therefore, the target mean strength is calculated as-f'ck = 25 + 1.65×4 = 31.6 . OR. f'ck = 25 + 5.5 = 30.5. Thus, the mean target strength is 31.6 N/sqmm (higher value of the above two calculations).
