Math Problem Statement

One says, "Give me a hundred rupee, friend! I shall then become twice as rich as you are." The other replies, "If you give me ten rupees, I shall be six times as rich as you are." Tell me how much money both have initially?

Solution

Let the amount of money the first person has be xx, and the amount of money the second person has be yy.

First Condition:

The first person says that if the second person gives them 100 rupees, they will become twice as rich as the second person. This can be written as: x+100=2(y100)x + 100 = 2(y - 100) Simplifying the equation: x+100=2y200x + 100 = 2y - 200 x=2y300(Equation 1)x = 2y - 300 \quad \text{(Equation 1)}

Second Condition:

The second person says that if the first person gives them 10 rupees, they will be six times as rich as the first person. This can be written as: y+10=6(x10)y + 10 = 6(x - 10) Simplifying the equation: y+10=6x60y + 10 = 6x - 60 y=6x70(Equation 2)y = 6x - 70 \quad \text{(Equation 2)}

Solving the System of Equations:

Now, substitute the expression for xx from Equation 1 into Equation 2:

y=6(2y300)70y = 6(2y - 300) - 70 Expanding: y=12y180070y = 12y - 1800 - 70 y=12y1870y = 12y - 1870 Rearranging the terms: 1870=11y1870 = 11y y=187011=170y = \frac{1870}{11} = 170

Now substitute y=170y = 170 into Equation 1 to find xx: x=2(170)300=340300=40x = 2(170) - 300 = 340 - 300 = 40

Final Answer:

  • The first person has 40 rupees.
  • The second person has 170 rupees.

Here are 5 relative questions for further exploration:

  1. How would the problem change if the first person asked for 200 rupees instead of 100?
  2. Can this problem be generalized to a similar one involving three people?
  3. How would the equations change if both people had the same amount of money at the start?
  4. What would happen if we solved this problem with different currencies instead of rupees?
  5. How does this system of linear equations relate to real-life financial transactions?

Tip: Always verify your solutions by substituting them back into the original conditions.
