Answer 2

Given: Richa and Sheenu have a certain amount with them . If sheenu gives 20 to richa she will have half the amount with richa. if richa gives 40 to sheenu she will have half the amount with sheenu.

To find: The amount with sheenu.

Solution:

Let the amount with Richa and Sheenu be equal to x and y, respectively. According to the question, when Sheenu gives 20 to Richa she will have half the amount with Richa. This can be written in the form of an equation as shown below.

$(y-20) = \frac{1}{2} (x+20)$

This equation can be simplified and written as follows.

$x- 2y = -60$

Also, when Richa gives 40 to Sheenu, she will have half the amount with Sheenu. This can be written in the form of an equation as shown below.

$(x-40) = \frac{1}{2} (y+40)$

This equation can be simplified and written as follows.

$2x-y=120$

Now, the two simplified equations can be solved simultaneously and the values of x and y are found to be

$x=100$

$y=80$

Therefore, the amount with Sheenu is 80.
