The given problem is based on addition and subtraction concepts.

Answer: The total sales in 2 weeks was of Rs. 685889. The sales in the second week was more than the sale in the first week by Rs.115647.

Let's interpret the information mathematically.

Explanation:

The value of sales in the first week of June = Rs. 285121

The value of sales in the second week of June = Rs. 400768

The total value of sales in two weeks = 285121 + 400768 = Rs. 685889

The sale in the second week is higher as 400768 is greater than 285121.

The hike of sales in the second week = 400768 - 285121 = Rs. 115647.

Thus, The total sales in 2 weeks was of Rs. 685889. The sales in the second week was more than the sale in the first week by Rs.115647.
