Question

The pictograph shows the sales of cars in 4 weeks by a car dealer. The pictograph is incomplete.

Key: Each represents 2 cars.
If 4 more cars were sold in week 3 than in week 1, how many must be drawn in the pictograph above for week 3?

• A. 2
• B. 5
• C. 8
• D. 6

Answer 1

The correct option is B 5

Eachrepresents 2 cars.
$\Rightarrow$Number of cars sold in week 1 $=3\times 2=6$

4 more cars were sold in week 3 than in week 1.
$\Rightarrow$ Number of cars sold in week 3
= 6 + 4 = 10
Since 2 cars are represented by 1 symbol, 10 cars would be represented by $\frac{10}{2}=5$ symbols.
