- 50000 tonnes
- 50000000 tonnes
- 5000000 tonnes
- 500000 tonnes
The Correct Option is D
Solution and Explanation
Production of company C in year \(1991 = 45,00,000\) tonnes
Production of company A in year \(1996 = 50,00,000\) tonnes
Difference between the production of company C in 1991 and the production of company A in 1996,\(= 50,00,000-45,00,000\)
\(= 5,00,000\) tonnes
So, the correct option is (D): \(500000\) tonnes.
What is the per centage increase in production of company A from 1992 to 1993?
- 37.5
- 38.25
- 35
- 36
The Correct Option is A
Solution and Explanation
Percentage increase in production of company A from \(1992\) to \(1993\),
\(= \frac {55-40}{40} \times 100\)
\(=\frac {15}{40} \times 100\)
\(=37.5\%\)
So, the correct option is (A): \(37.5\%\)
For which of the following years was the percentage of rise/fall in production from the previous year the maximum for company B?
- 1992
- 1993
- 1996
- 1995
The Correct Option is B
Solution and Explanation
Percentage of rise/fall in production from the previous year for company B in year 1992,
\(=\frac {60-55}{55} \times 100 = 9.09\%\)
Percentage of rise/fall in production from the previous year for company B in year 1993,
\(=\frac {50-60}{50} \times 100 = -16.67\%\) (Maximum)
Percentage of rise/fall in production from the previous year for company B in year 1996,
\(=\frac {55-50}{50} \times 100 = 10\%\)
Percentage of rise/fall in production from the previous year for company B in year 1995,
\(=\frac {50-55}{55} \times 100 = -9.09\%\)
So, the correct option is (B): \(1993\).
The total production of company C in 1993 and 1994 is what percentage of the total production of company Ain 1991 and 1992?
- 95
- 90
- 110
- None of these
The Correct Option is D
Solution and Explanation
Total production of company C in year \(1993\) and year \(1994 = 60+60 = 120\)
Total production of company A in year \(1991\) and year \(1992 = 50+40 = 90\)
Now, required \(\% = \frac {120}{90} \times 100 = 133.33\%\)
So, the correct option is (D): None of these.
What is the difference between the average production per year of the company with highest average production and that of the company with lowest average production in lakh tonnes?
- 3.17
- 4.33
- 4.17
- 3.33
The Correct Option is C
Solution and Explanation
Production of Paper by company \(A = 50+40+55+45+60+50 = 300\) lakh tonnes
Production of Paper by company \(B = 55+60+50+55+50+55 = 325\) lakh tonnes
Production of Paper by company \(C = 45+50+60+60+45+40 = 300\) lakh tonnes
Now, required average difference \(= \frac {325-300}{6} = 4.17\)
So, the correct option is (C): \(4.17\)
