(c) On which of the days same number of bulbs were sold?
(d) On which of the days minimum number of bulbs were sold?
(e) If one big carton can hold 9 bulbs. How many cartons were needed in the given week?

Solution:

We use the concept of data handling to answer the given questions.

(a) On Friday, a total of 14 bulbs were sold.

(b) On Sunday, a total of 18 bulbs were sold.

Hence, the maximum number of bulbs was sold on Sunday.

(c) 8 bulbs are sold on Wednesday and Saturday.

Hence, on both Wednesday and Saturday, an equal number of bulbs were sold.

(d) 8 bulbs are sold on Wednesday and Saturday.

Hence, the Minimum number of bulbs was sold on Wednesday and Saturday.

(e) A total of 86 bulbs were sold in the given week.

⇒ 12 + 16 + 8 + 10 + 14 + 8 + 18 = 86

Since one big carton can hold 9 bulbs, we would require

⇒ 86/9 ≈ 10 cartons

∴ 10 cartons were needed in the given week.
