If Fatima has an equal number of notes of denomination 10, 5 and 2 and...
To solve this problem, we can use the concept of algebraic equations. Let's assume the number of notes of denomination 10, 5, and 2 as 'x'.
Given:
Number of notes of denomination 10 = Number of notes of denomination 5 = Number of notes of denomination 2 = x
Total amount = Rs. 510
We can form the following equations based on the given information:
Equation 1: 10x + 5x + 2x = 510
This equation represents the sum of the values of all the notes.
Simplifying Equation 1, we get:
17x = 510
Dividing both sides by 17:
x = 30
So, the number of notes of each denomination is 30.
Explanation:
- The given information states that Fatima has an equal number of notes of denomination 10, 5, and 2.
- Let's assume the number of notes of each denomination as 'x'.
- Since the number of notes is equal for each denomination, we can express the number of notes of each denomination as 'x'.
- The total amount is given as Rs. 510.
- We can form an equation by multiplying the number of notes of each denomination by their respective values and adding them together.
- Simplifying the equation, we find that x = 30, which means Fatima has 30 notes of each denomination.
- Therefore, the correct answer is option 'C' - 30.
