Let us make the following 2 assumptons for Option 1 :
i. If the contractor worked for 11 hours, then the wage W would be r*2 + r*0.2*3 = 2.6r.
ii. If the contractor worked for 9 hours, then the wage W would be r*2 + r*0.2*1 = 2.2r.
Now, going by option 1) W = 288$
So, If i. => 2.6r = 288$ => r > 100 (allowed as per question)
But if ii => 2.2r ==288$ +> r >100 (allowed as per question)
Which means that we cannit tell if the contarctor worked for more than 10 (11) or less than 10(9) hours. So Option 1 is insufficient.
For Option 2)
If the contractor worked for 10 hours, then the wage W would be r*2 + r*0.2*2 = 2.4r, which is exactly what Option 2 says, whuch means the contractor worked for exactly 10 hours. So, sufficient.
P.S. Kudos if you liked my solution.
