Question

Kirti Bookstore sold books worth $\mathrm{Rs}2,85,891$ in the first week of June and books worth $\mathrm{Rs}4,00,768$ 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?

Answer 1

Step 1: Compute the total sales for two weeks:

Value of books sold in the first week $=\mathrm{Rs}2,85,891$

Value of books sold in the second week $=\mathrm{Rs}4,00,768$

Total sales of two weeks

$$\begin{gathered} =2,85,891+4,00,768 \\ =\mathrm{Rs}6,86,659 \end{gathered}$$

Step 2: Find the difference between the first and second week:

Clearly, the week $2$ has greater sales than a week $1$.

The difference in sales $=$Week2 $-$ Week1

$$\begin{gathered} =4,00,768-2,85,891 \\ =1,14,877 \end{gathered}$$

The sale of the week $2$ is $\mathrm{Rs}1,14,877$ greater than a week$1$.

Hence, sales for the week $2$ are greater than a week $1$by $\mathrm{Rs}1,14,877.$
