I say (A).

Diff of 180 $ is coming from 6 hrs....so hr rate = 30$/hr....but we don't know if it is rate of 40+ hrs or <=40 hrs.

Scenario 1:

If it is 40 hr rate then....let's say he does x hrs in that week, where x <=40

30*X = 960 .....X = 32 hrs...meaning he wud have worked....

32-6 = 26 hrs

Scenario 2:

If the above rate is for > 40 hrs....then let's say he works for X hrs extra originally, where total hrs if > 40....X representing the additional hrs ,now

40*15 (for first 40 hrs) + (X+6) *30 = 960

20 + X+6 = 32 ....X = 6 hrs.....so original hrs....40+6 = 46 hrs

Scenario 1 yields different result as 2...so insuff....
