Study the following graph carefully and answer the questions given below:
The total production in which of the following pairs of years is equal to 25 per cent of total production in all the years together ?
I. 1998 and 2004
II. 1998 and 2003
III. 1999 and 2001
In thousand metric tonnes:
Production in 1998 = 15
Production in 1999 = 50
Production in 2000 = 30
Production in 2001 = 45
Production in 2002 = 65
Production in 2003 = 75
Production in 2004 = 70
So, the total = 350
350 * 25% = 87.5
None of the above is the correct answer.
