Since reported is the past and the past perfect (or past of the past) is what they reported on. The part after semicolon is an explanation of what they reported on. The statement does not have anything to do with what happened after scientists reported. (We would have had 'scientists had reported', if that were the case)

1) First one - $20 is the average. So Husain + Dino = 20*2 = 40 Since new average = 80, Husain + Dino = 80*2 = 160. Increase = 160-40 = 120. So Dino won 120. 2) 60 is exactly midway between 40 and 80. Hence, she will have to work as many hours at $80/week as she works at $40/week. So 40 hours at $80/hr should do it. Total work = 80 hours. 3) The language of the question would indicate that. Try to understand what the question is saying and you would know intuitively what to do. 4) Assume distance to be 330 miles (any number which is a multiple of 22 and 30 should do). In going it will take 330/22 = 15 gallons. In coming back it would take 330/30 = 11 gallons. Total fuel consumed = 26 gallons. total distance travelled = 660 miles. Average mileage = 660/(26) miles per gallon.
