Observe the pictograph and answer the following questions:
- How many bulbs were on Friday?
- On which day maximum number of bulbs were sold?
- If one bulb was sold at the rate of Rs 10, what was the total earning on sunday?
- Can you find out the total earning of the week?
- If one big carton can hold 9 bulbs. How many cartons were needed in the given week, more than 7, more than 8 or more than 9?
Answer
Therefore, Total number of bulbs sold on Friday = 2 × 7 = 14
Given, the cost of each bulb = ₹ 10
Therefore, Total earning on Sunday = ₹ 10 × 18 = ₹ 180
Therefore, Total number of bulbs = 43 × 2 = 86
Therefore, Total earning of the week = ₹ 10 × 86 = ₹ 860.
Therefore, for holding 86 bulbs, we need
869 = 959 cartons
So, more than 9 cartons are needed.
View full question & answer→- Number of figures of bulbs shown against Friday = 7
Therefore, Total number of bulbs sold on Friday = 2 × 7 = 14
- Sunday shows the maximum number of figure of bulbs, i.e. 9
- Number of figures of bulbs shown against Sunday = 9
Given, the cost of each bulb = ₹ 10
Therefore, Total earning on Sunday = ₹ 10 × 18 = ₹ 180
- Total number of figures of bulbs shown throughout the week
Therefore, Total number of bulbs = 43 × 2 = 86
Therefore, Total earning of the week = ₹ 10 × 86 = ₹ 860.
- Total number of bulbs = 86
Therefore, for holding 86 bulbs, we need
869 = 959 cartons
So, more than 9 cartons are needed.
