Statement 1:
(1) Net profit during the third year was half as much as during the fifth year.
NP(3rd year) = (1/2)* NP(5th year)
if NP(5th year) = 2a
NP(3rd year) = a
Hence, insufficient Statement 2:
(2) Net profit during the fourth year was $12 million more than during the third year.
NP(4th year) = NP(3rd year) + $12 million.
No information pertaining to third year is given.
Hence, insufficient
combining both statements , we get
NP(4th year) = NP(3rd year) + $12 million.
NP(4th year) = a + $12 million.
since, we don’t know a. We can’t find the net profit for fourth year.
