Answers
Answer:Rs 100-notes=2000
Rs 50-notes=3000
Rs 10-notes=50
Explanation: Let the number of : Rs 100-notes=2
Rs 50-notes=3
Rs 10-notes=5
value of Rs 100-notes=2 ×Rs 100
Rs 200
Value of Rs 50-notes=3×Rs 50= Rs 150
value of Rs 10 we have 10-notes=5×Rs
10 =Rs 50
According to the condition we have Rs
200+Rs 150+Rs 150 + Rs 50=Rs 400000
OR 200+150+50=400000
OR 400=400000
Dividing both sides by 400 we have =400000÷400=1000
2=2x1000=2000
3=3x=1000=3000
5=5x1000=5000
Rs 100-notes=2000
Rs 50-notes=3000
Rs 10-notes=5000
Let the numbers of notes of ₹100, ₹50 and ₹10 be 2x, 3x and 5x respectively.
- Value of ₹100 = 2x × 100 = 200x
- Value of ₹50 = 3x × 50 = 150x
- Value of ₹10 = 5x × 10 = 50x
According to the question,
200x + 150x + 50x = 4,00,000
⇒ 400x = 4,00,000
⇒ x = 400000/400
⇒ x = 1000
Numbers of ₹100 notes = 2x = 2000
Numbers of ₹50 notes = 3x = 3000
Numbers of ₹10 notes = 5x = 5000
