Question 147

Study the pie chart and answer the question.
Distribution (degree wise) of the number of computers sold by a shopkeeper during five months.

The total number of computers sold in February and April is what percentage more than the number of computers sold in May? (Your answer should be correct to one decimal place.)

Solution

in february = $$ \dfrac {45}{360} \times 5400 $$

$$\Rightarrow 675 $$

In april $$ \dfrac{54}{360} \times 5400$$

$$\Rightarrow 810 $$

again may = $$\dfrac{77}{360} \times 5400 $$

$$\Rightarrow 1155 $$

then total computers in February + April = 675 + 810 = 1485

so % more than computers = $$\dfrac{ 1485- 1155}{1155}\times 100$$

$$\Rightarrow \dfrac{330}{1155} \times 100 $$

$$\Rightarrow 28.6 $$ Ans
