Question

The pictogram shows the number of calculators sold by a shop over three days. A total of Rs. $600$ was collected from the sale of calculators on Monday.Which of the following statements is correct?

• A. The price of each calculator is Rs. $50$
• B. The total sales made over the $3$ days amounted to Rs. $1800$
• C. $60$ calculators were sold on Tuesday
• D. The difference between the sales on Tuesday and Wednesday is Rs. $200$

Answer 1

The correct option is B The total sales made over the $3$ days amounted to Rs. $1800$

As each key represents $5$ calculators, $5\times 4=20$ calculators were sold on Monday.
As Rs. $600$ was collected on Monday, cost of each calculator $=\frac{600}{20}=$ Rs. $30$
The total number of calculators sold on all three days $=12$ keys $\times 5=60$.
Total money collected in three days $=60\times$ Rs. $30=$ Rs. $1800$.
