Correct Answer: 1995 and 2001


Solution : Average production (in 10000 tonnes) of 1996 and 1997 = $\frac{40+60}{2}$ = 50
We shall find the average production (in 10000 tonnes) for each of the given alternative pairs:
Average production (in 10000 tonnes) of 2000 and 2001 = $\frac{50+75}{2}$ = 62.5
Average production (in 10000 tonnes) of 1999 and 2000 = $\frac{65+50}{2}$ = 57.5
Average production (in 10000 tonnes) of 1995 and 1999 = $\frac{25+65}{2}$ = 45
Average production (in 10000 tonnes) of 1995 and 2001 = $\frac{25+75}{2}$ = 50
∴ The average production of 1996 and 1997 is equal to the average production of 1995 and 2001.
Hence, the correct answer is 1995 and 2001.
