- The total sales of all the seven years is the maximum for which battery?
A. 4AH
B. 7AH
C. 32AH
D. 35AH
Answer: C. 32AH
Explanation: The total sales (in thousands) of all the seven years for various batteries are:
For 4AH = 75 + 90 + 96 + 105 + 90 + 105 + 115 = 676
For 7AH = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694
For 32AH = 114 + 102 + 75 + 150 + 135 + 165 + 160 = 901
For 35AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601
For 55AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.
Clearly, sales are maximum in case of 32AH batteries. - What is the difference in the number of 35AH batteries sold in 1993 and 1997?
A. 24,000
B. 28,000

A. 1994
B. 1995
C. 1996
D. 1997
Answer: D. 1997
Explanation:For 1992 = (75/543 x 100)% = 13.81%.
For 1993 = (90/528 x 100)% = 17.05%.
For 1994 = (96/525 x 100)% = 18.29%.
For 1995 = (105/510x 100)% = 20.59%.
For 1996 = (96/465 x 100)% = 19.35%.
For 1997 = (105/495 x 100)% = 21.21%.
For 1998 = (115/605 x 100)% = 19.01%.
Clearly, the percentage is maximum in 1997. - In the case of which battery was there a continuous decrease in sales from 1992 to 1997?
A. 4AH
B. 7AH

The percent profit or loss of a company is given by ( % Profit/Loss =Income – Expenditure/ Expenditure x 100) Income and Expenditure (in million US $) of five companies in the year 2001.
- The companies M and N together had a percentage of profit/loss of?
A) 12% loss
B) 10% loss
C) 10% profit
D) There was no loss or profit
Answer: D
Explanation:
Total income of Companies M and N together
= (35 + 50) million US $
= 85 million US $
Total expenditure of Companies M and N together
= (45 + 40) million US $
= 85 million US $.
Therefore Percent Profit/Loss of companies M and N together
% Profit/Loss = (85 – 85/85 x 100) = 0%.
Thus, there was neither loss nor profit for companies M and N together - In 2001, what was the approximate percentage of profit/loss of all the five Companies taken together?
A) 5% profit
B) 6.5% profit
C) 4% loss
D) 7% loss
Answer: A
Explanation:
Total income of all five companies
= (35 + 50 + 40 + 40 + 50) million US $
= 215 million US $.
Total expenditure of all five companies
= (45 + 40 + 45 + 30 + 45) million US $
= 205 million US $.
Therefore % Profit = [(215 – 205)/205 x 100] % = 4.88% ~= 5%. - Which company earned the maximum percentage profit in the year 2001?
A) M
B) N
C) P
D) Q
Answer: D
Explanation: The percentage profit/loss in the year 2001 for various comapanies are:
For M =[ (35 – 45)/ 45 x 100 ] % = -22.22% i.e., Loss = 22.22%.
For N = [(50 – 40)/ 40 x 100] % = 25% i.e., Profit = 25%.
For P = [ (40 – 45)/45 x 100] % = -11.11% i.e., Loss = 11.11%.
For Q = [(40 – 30)/30 x 100] % = 33.33% i.e., Profit = 33.33%.
For R =[(50 – 45)/45 x 100]% = 11.11% i.e., Profit = 11.11%.
Clearly, the Company Q earned the maximum profit in 2001. - For Company R, if the expenditure had increased by 20% in year 2001 from year 2000 and the company had earned a profit of 10% in 2000, what was the Company’s income in 2000 (in million US $)?
A) 35.75
B) 37.25
C) 38.5
D) 41.25
Answer: D
Explanation: Let the expenditure of Company R in 2000 be X million US $.
Then, expenditure of Company R in 2001 = (120/100x X) million US $.
Therefore 120X/100 = 45 => X = 37.5.
i.e., expenditure of Company R in 2000 = 37.5 million US $.
Let the income of Company R in 2000 be I million US $.
Then, 10 = (I – 37.5)/ 37.5 x 100 [ %Profit in 2000 = 10%]
=> I – 37.5 = 3.75
=> I = 41.25
i.e., Income of Company R in 2000 = 41.25 million US $. - If the income of Company Q in 2001 was 10% more than its income in 2000 and the Company had earned a profit of 20% in 2000, then its expenditure in 2000 (in million US $) was?
A) 28.28
B) 30.30
C) 32.32
D) 34.34
Answer: B
