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
