Answer 1

Answer:

This is just Algebra basically. Initially you might think you need two equations to solve such a problem ( as it has two variables ), by just looking at the statement. I thought the same. But I will show you that you don't need two equations to solve this question, since the question is designed in that manner. Let me you walk through the solution.

Step-by-step explanation:

18 Apples and 45 Mangoes cost Rs. 981.

Now, let X be one apple's cost, and Y be one mango's cost. Form an equation with this.

18X + 45Y = 981

You can cancel out a factor of 9 on both sides

9 * ( 2X + 5Y ) = 9 * 109

2X + 5Y = 109

The above is the simplified equation.

Now, multiply 5 on both sides of the equation.

5 * ( 2X + 5Y ) = 5 * 109

10X + 25Y = 545

The above equation means : 10 Apples and 25 Mangoes cost Rs. 545.

That's the answer to your question ! Which is Rs 545
