Answer:
The number of 100 Rs. notes = 5
The number of 50 Rs. notes = 15
The number of 10 Rs. notes = 20
Step-by-step explanation:
Let,
The number of 100 Rs. notes = x
The number of 50 Rs. notes = 3x
The number of 10 Rs. notes = 4x
★ Value of notes :
- 100 (x) = 100x
- 50 (3x) = 150x
- 10 (4x) = 40x
Total amount he has Rs. 1,450 (Given)
★ According to the Question :
⇒ 100x + 150x + 40x = 1,450
⇒ 290x = 1,450
⇒ x = 1,450 / 290
⇒ x = 5
The number of 100 Rs. notes = 5
The number of 50 Rs. notes = 3x
⇒ 3 (5)
⇒ 15
The number of 50 Rs. notes = 15
The number of 10 Rs. notes = 4x
⇒ 4 (5)
⇒ 20
The number of 10 Rs. notes = 20
Therefore,
The number of 100 Rs. notes = 5
The number of 50 Rs. notes = 15
The number of 10 Rs. notes = 20
