• A. 17.5
• B. 25.3
• C. 24.4
• D. 21.2

Hint:

In data-interpretation percentage comparison problems, always identify the correct base value before applying the percentage formula.

Answer 1

The Correct Option is D

Step 1: Note the cars sold by dealer P from February to June.
From the table:
February = 94
March = 85
April = 108
May = 98
June = 95
Step 2: Find the total cars sold by P from February to June.
\[ 94 + 85 + 108 + 98 + 95 = 480 \]
Step 3: Find the total cars sold by all dealers in June.
From the table, total cars sold in June = 396
Step 4: Find the difference between the two quantities.
\[ 480 - 396 = 84 \]
Step 5: Apply percentage more formula.
Percentage more is calculated as:
\[ \frac{\text{Difference}}{\text{Original value}} \times 100 \]
Step 6: Substitute the values.
\[ \frac{84}{396} \times 100 \]
Step 7: Simplify the calculation.
\[ \frac{84}{396} = \frac{7}{33} \]
\[ \frac{7}{33} \times 100 \approx 21.21% \]
Step 8: Final conclusion.
Hence, the total number of cars sold by P during February to June is approximately 21.2% more than the total number of cars sold by all dealers in June.
