Question

The sale of electric bulbs on different days of a week is shown below :Observe the pictograph and answer the following questions :
If one big carton can hold 9 bulbs. How many cartons were needed in the given week?

Answer 1

numbers of bulbs sold from Monday to sunday are as follows:

Monday = 6×2 =12
Tuesday = 8×2 = 16
Wednesday= 4×2 = 8
Thursday = 5×2 = 10
Friday = 7×2 = 14
Saturday = 4 ×2 = 8
sunday = 9×2 = 18

Total numbers of bulbs sold = 12 + 16 + 8 + 10 + 14 + 8 + 18 = 86

Number of bulbs one carton can hold = 9

Number of cartons needed to hold 86 bulbs = 86 ÷ 9 = 9, 5 bulbs will remain

We need one extra carton to keep the 5 bulbs.

So total cartons = 9 +1 = 10

Thus, we need 10 cartons in the given week

Answer 2

Hey there !

Solution:

Let us calculate the total number of bulbs sold in the last week.

• Monday = 6 bulbs
• Tuesday = 8 bulbs
• Wednesday = 4 bulbs
• Thursday = 5 bulbs
• Friday = 7 bulbs
• Saturday = 4 bulbs
• Sunday = 9 bulbs

Total Number of Bulbs sold in that week = 6 + 8 + 4 + 5 + 7 + 4 + 9 = 43 bulbs

So 1 carton = 9 bulbs

=> x cartons = 43 bulbs

=> 9 × x = 43 × 1

=> x = 43 / 9

=. x = 4.7 cartons

But cartons cannot be a fraction. So rounding it off to the next nearest number, we get the number of cartons to be 5.

Hence the number of cartons needed in that week were 5.

Hope my answer helped !
