Question 15 Marks
The sale of electric bulbs on different days of a week is shown below:

Observe the pictograph and answer the following questions:
$i.\ $How many bulbs were on Friday?
$ii.\ $On which day maximum number of bulbs were sold?
$iii.\ $If one bulb was sold at the rate of $Rs\ 10$, what was the total earning on sunday?
$iv.\ $Can you find out the total earning of the week?
$v.\ $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
 
$i.\ $Number of figures of bulbs shown against Friday $= 7$
Given, $1$ figure $= 2$ bulbs
Therefore, Total number of bulbs sold on Friday $= 2 \times 7 = 14$
$ii.\ $Sunday shows the maximum number of figure of bulbs, i.e. $9$
Therefore, On Sunday, maximum bulbs were sold.
$iii.\ $Number of figures of bulbs shown against Sunday $= 9$
Therefore, Total number of bulbs sold on Sunday $= 2 \times 9 = 18$
Given, the cost of each bulb $= ₹ 10$
Therefore, Total earning on Sunday $= ₹ 10 \times 18 = ₹ 180$
$iv.\ $Total number of figures of bulbs shown throughout the week
$= 6 + 8 + 4 + 5 + 7 + 4 + 9 = 43$
Therefore, Total number of bulbs $= 43 \times 2 = 86$
Therefore, Total earning of the week $= ₹ 10 \times 86 = ₹ 860.$
$v.\ $Total number of bulbs $= 86$
Given that one big carton can hold $9$ bulbs.
Therefore, for holding $86$ bulbs, we need
$869 = 959$ cartons
So, more than $9$ cartons are needed.
