The table given below shows the average number of articles (A, B and C) sold by Pesto company in three different months. It also shows the percentage of article A sold by Pesto company out of the total number of articles sold in these months. Table also reflects the total number of article C sold in these months. Read the table carefully and answer the following questions.

Months	Average number of articles sold	Percentage of article A sold	Total number of articles C sold
April	100	40%	100
May	120	30%	70
June	72	25%	80

In month of July, total number of articles A sold by Pesto are 25% more than the average number of articles B sold in the month of May and June. If the sum of the article B and C sold by Pesto in July are 30% more than the articles B sold by Pesto in April, then find the difference in the number of articles B sold in July to that of in April.

The correct option is Can’t be determined.

Step 1: Understand the given data from the table

The table provides information about three articles (A, B, and C) sold by Pesto company in April, May, and June:

1. April:

Average number of articles sold = 100

Total number of articles (A + B + C) = $100\times 3=300$

Percentage of article A sold = 40% of 300 = $0.40\times 300=120$

Total number of article C sold = 100

Therefore, total number of article B sold in April = Total articles - Article A - Article C

$\text{Article B (April)}=300-120-100=80$

2. May:

Average number of articles sold = 120

Total number of articles (A + B + C) = $120\times 3=360$

Percentage of article A sold = 30% of 360 = $0.30\times 360=108$

Total number of article C sold = 70

Therefore, total number of article B sold in May = $360-108-70=182$

3. June:

Average number of articles sold = 72

Total number of articles (A + B + C) = $72\times 3=216$

Percentage of article A sold = 25% of 216 = $0.25\times 216=54$

Total number of article C sold = 80

Therefore, total number of article B sold in June = $216-54-80=82$

Step 2: Analyze the conditions given for the month of July

We are given that:

- Sum of article B and article C sold in July = 30% more than article B sold in April.

$\text{Article B (July)}+\text{Article C (July)}=1.30\times \text{Article B (April)}$

$\text{Article B (July)}+\text{Article C (July)}=1.30\times 80=104$

Step 3: Evaluate if Article B (July) can be uniquely calculated

We have the combined total of article B and article C sold in July, which is equal to 104:

$\text{Article B (July)}+\text{Article C (July)}=104$

However, there is no additional information or individual breakdown provided to separate the value of article B sold in July from article C sold in July.

Since the exact number of article B sold in July depends on the number of article C sold in July (which is unknown), the exact value of article B sold in July—and consequently the difference between article B sold in July and April—cannot be determined.
