In a certain coding system, 'competitive success rate'

Solution

'competitive success rate' is coded as 'gb, ew, nm' ……… (i) 'rate half test' is coded as 'fv, az, nm' ………… (ii) 'test competitive scores' is coded as 'lk, az, ew'……….. (iii) From (i) and (ii), we will get the code for ‘rate’ is nm From (i) and (iii), we will get the code for ‘competitive’ is ew From (ii) and (iii), we will get the code for ‘test’ is az Now we get the code for ‘success’ is gb. Now we get the code for ‘half’ is fv. Now we get the code for ‘scores’ is lk. So, the code for ‘competitive half scores’ is  ew fv lk.
