per captia fish consumed = Total Fish consumed/ Total population
We shall take few cases to prove E is correct.
In 1980 : Total Fish consumed : 5000 Kgs
Total population : 100 people
per captia fish consumed = 50
In1989 : Total Fish consumed ; 5000 + 4.5 % ( 5000)
= 5022.5
Total Population : 100 + 6% ( 100)
: 106
per captia fish consumed : 5022.5/106
: 47.38
50 > 47.38 : Per capita consumption of fish in Jurania was lower in 1989 than in 1980
SO E does that!!
