Kirti Bookstore sold books worth ₹2,85,891 in the first week of June and books worth ₹4,00,768 in the second week of the month. How much was the sale for the two weeks together? In which week was the sale greater and by how much?

Books sold in first week = 2,85,891
Books sold in second week = + 4,00,768
Total books sold = 6,86,659
Since, 4,00,768,> 2,85,891
Therefore sale of second week is greater than that of first week.
Books sold in second week = 4,00,768
Books sold in first week = – 2,85,891
More books sold in second week = 1,14,877
Therefore, 1,14,877 more books were sold in second week.
