Answer 1

The Correct Option is A

Concept: In a pie chart: \[ 360^\circ = 100\% \] So percentage share is calculated as: \[ \frac{\text{Sector angle}}{360}\times100 \]

Step 1: Find DELL’s angle.
Given sectors: \[ HP=110^\circ \] \[ HCL=60^\circ \] \[ ACER=70^\circ \] \[ ZENITH=35^\circ \] \[ OTHERS=55^\circ \] Total known: \[ 110+60+70+35+55=330^\circ \] So DELL: \[ 360-330=30^\circ \]

Step 2: Convert into percentage.
\[ \frac{30}{360}\times100 \] \[ =\frac{1}{12}\times100 \] \[ =\frac{100}{12} \] \[ =8\frac{1}{3}\% \] Hence, the market share of DELL is: \[ \boxed{8\frac{1}{3}\%} \]

Answer 2

Concept: In a pie chart, the share of a category is: \[ \frac{\text{Sector angle}}{360^\circ}\times \text{Total quantity} \]

Step 1: Take ACER’s angle from the pie chart.
ACER share: \[ 70^\circ \] Total computers sold: \[ 270000 \]

Step 2: Apply the formula.
\[ \text{ACER sales}=\frac{70}{360}\times270000 \] \[ =\frac{7}{36}\times270000 \]

Step 3: Simplify.
\[ 270000 \div 36=7500 \] \[ 7500\times7=52500 \] Thus, the number of computers sold by ACER is: \[ \boxed{52500} \]

Answer 3

Concept: To find how much percent one quantity is more than another: \[ \frac{\text{Difference}}{\text{Base value}} \times 100 \] Here, HP is compared with ZENITH.

Step 1: Take values from the pie chart.
HP share: \[ 110^\circ \] ZENITH share: \[ 35^\circ \]

Step 2: Find the difference.
\[ 110-35=75 \]

Step 3: Calculate percentage more than ZENITH.
\[ \frac{75}{35}\times100 \] \[ =\frac{15}{7}\times100 \] \[ =\frac{1500}{7} \] \[ =214\frac{2}{7}\% \] Thus, HP sold more computers than ZENITH by: \[ \boxed{214\frac{2}{7}\%} \]
