1. What was the approximate percentage increase in the sales of 55AH batteries in 1998 compared to that in 1992 ?
- 31%
- 33%
- 34%
- 36%
Answer :
Option C
Explanation:
Increase is = 145-108 = 37
Now we need to calculate that 37 is what percent of 108.
\begin{aligned}
\left(\frac{37}{108}*100 \right)\%
= 34.25\%
\end{aligned} -

4. The total sales of all the seven years is the maximum for which battery ?
- 35 AH
- 4 AH
- 7 AH
- 32 AH
Answer :
Option D
Explanation:
The total sales (in thousands) of all the seven years for various batteries
are : a t.
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 35 AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601
For 55 AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.
Clearly, sales are maximum in case of 32AH batteries.
