Answer 1

Answer:

The number of notes of Rs 100 = 9 notes

The number of notes of Rs 200 = 7 notes

Explanation:

Let,

The number of notes of Rs 100 = x

The total number of notes = 16

The number of notes of Rs 200 = (16 - x)

Total amount = Rs 2,300

★ According to the question :

⇒ 100 (x) + 200 (16 - x) = 2,300

⇒ 100x + 3,200 - 200x = 2,300

⇒ 100x - 200x = 2,300 - 3,200

⇒ - 100x = - 900

⇒ 100x = 900

⇒ x = 900 / 100

⇒ x = 9

The number of notes of Rs 100 = 9 notes

____________________________

The number of notes of Rs 200 = (16 - x)

⇒ 16 - x

⇒ 16 - 9

⇒ 7

The number of notes of Rs 200 = 7 notes

Therefore,

The number of notes of Rs 100 = 9 notes

The number of notes of Rs 200 = 7 notes
