Final answer:
Pihu has 28 ₹500 notes and 57 ₹100 notes in her bag.
Step-by-step explanation:
To solve this problem, let's use algebra. Let's assume that the number of ₹500 notes is 'x'. According to the problem, the number of ₹100 notes is one more than twice the number of ₹500 notes. So, the equation would be:
₹100 notes = 1 + 2x
Now, let's find the total value of the ₹100 notes and the ₹500 notes:
Value of ₹100 notes = ₹100 * (1 + 2x) = ₹100 + ₹200x
Value of ₹500 notes = ₹500 * x = ₹500x
The total value of the money in her bag is given as ₹8500. So, the equation becomes:
₹100 + ₹200x + ₹500x = ₹8500
Combining like terms, we get:
₹300x + ₹100 = ₹8500
Subtracting ₹100 from both sides:
₹300x = ₹8400
Dividing both sides by ₹300:
x = 28
So, Pihu has 28 ₹500 notes and the number of ₹100 notes would be 1 + 2 * 28 = 57.
