We are asked about the hours worked today.

Statement 1) tells us he got paid 25$ more than yesterday.

The given hourly rate in the question stem is a multiple of 10, so it cannot be possible that he worked 8 hours or less it must be more.

5/4 * 10 = 12.5 for him to earn 25 more he has to work at least 10 hours.

8 * 10 = 80 + 12.5*2 = 105

However it could also be true that he worked 12 hours

80 + 50 = 130

Example: yesterday 8 hours and today 10 hours or yesterday 10 hours and today 12 hours etc..

Insufficient.

Statement 2) tells us he wokred 8 hours but we know nothing about today insufficient.

Combined we get an answer.

We know he worked for 10 hours.

Sufficient answer choice C
