Introduction

In a heartwarming gesture, Ram and Raman have decided to donate money to a blind school. However, they are being secretive about the actual amount they have contributed. To maintain their anonymity, they have chosen to use code words to represent the amounts they have donated. Ram has donated an amount represented by the expression (x+2y), while Raman has donated an amount represented by the expression (x-y). In this article, we will delve into the world of algebra and crack the code to find the total amount donated by Ram and Raman in terms of x and y.

The Code Words

Let's start by analyzing the code words used by Ram and Raman.

Ram's Donation: (x+2y)
Raman's Donation: (x-y)

These expressions seem simple, but they hold the key to unlocking the total amount donated by the duo.

Adding the Code Words

To find the total amount donated, we need to add the amounts donated by Ram and Raman. This can be represented by the expression:

(x+2y) + (x-y)

Using the distributive property of addition, we can simplify this expression:

x + 2y + x - y

Combining like terms, we get:

2x + y

So, the total amount donated by Ram and Raman is represented by the expression 2x + y.

Substituting Values

Now that we have the expression for the total amount donated, we can substitute the given values of x and y to find the actual amount.

Given: x = 10 y = 20

Substituting these values into the expression 2x + y, we get:

2(10) + 20 20 + 20 40

Therefore, the total amount donated by Ram and Raman is 40.

Conclusion

In this article, we have successfully cracked the code used by Ram and Raman to represent the amounts they have donated to a blind school. By analyzing the code words and using algebraic techniques, we have found the total amount donated by the duo in terms of x and y. We have also substituted the given values of x and y to find the actual amount donated. This puzzle serves as a reminder of the power of algebra in solving real-world problems.
