Harry withdraws ₹7500 from an ATM. He gets notes of ₹200 and ₹500 denominations. If the total number of notes is 24, then answer the following: The number of ₹200 notes is ------------- The number of ₹500 notes is --------------
Answers
Answer:
The numbers of ₹ 200 notes is 15
The numbers of ₹ 500 notes is 9
Step-by-step explanation:
Let,
The numbers of ₹ 200 notes = x
Total number of notes = 24
So,
The numbers of ₹ 500 notes = 24 - x
Total money = ₹ 7500
So,
So,
⇒ 200x + 500 (24 - x) = 7,500
⇒ 200x + 12,000 - 500x = 7,500
⇒ 200x - 500x = 7,500 - 12,000
⇒ - 300x = - 4500
⇒ 300x = 4500
⇒ x = 4500 / 300
⇒ x = 15
The numbers of ₹ 200 notes = 15
The numbers of ₹ 500 notes = 24 - x
⇒ 24 - 15
⇒ 9
The numbers of ₹ 500 notes = 9
Therefore,
The numbers of ₹ 200 notes is 15
The numbers of ₹ 500 notes is 9

★ Verification :
The total numbers of notes = 24
⇒ 15 + 9
⇒ 24
★ Total money = ₹ 7500
⇒ ₹ 200 notes = 15
⇒ 200 × 15
⇒ 3,000
⇒ ₹ 500 notes = 9
⇒ 500 × 9
⇒ 4,500
⇒ 3,000 + 4,500
⇒ ₹ 7500

Given:-
➢ Rupees withdrawn = ₹7500
➢ Total no. of notes = 24
Assumption:-
➲ Let the no. of ₹200 notes be x.
➲ So, the no. of ₹500 notes = 24-x.
Equation formed:-
★ 200(x) + 500(24-x) = 7500
Solution:-
⇢ 200x + 12000 - 500x = 7500
⇢ -300x = 7500 - 12000
⇢ -300x = -4500
⇢ x = -4500/-300
⇢ x = 15
➟ No. of ₹200 notes (x) = 15
➟ No. of ₹500 notes (24-x) = 9
∴ The number of ₹200 notes is 15.
∴ The number of ₹500 notes is 9.
