1.  For which model the percentage rise/fall in production from 2000 to 2001 was minimum?
A. Q
B. R
C. S
D. T
E. U

Answer: Option B

Explanation:

The percentage change (rise/fall) in production from 2000 to 2001 for various models is:

For P =[(176000 - 105000)x 100]% = 67.62%, rise.
105000

For Q =[(88000 - 52500)x 100]% = 67.62%, rise.
52500

For R =[(70000 - 66000)x 100]% = 5.71%, fall.
70000

For S =[(44000 - 35000)x 100]% = 25.71%, rise.
35000

For T =[(52500 - 44000)x 100]% = 16.19%, fall.
52500

For U =[(35000 - 22000)x 100]% = 37.14%, fall.
35000

Therefore Minimum percentage rise/fall is production is the case of model R.
