1. 100
2. 90
3. 105
4. 120

Answer 1

Correct Answer - Option 4 : 120

Let the Aman has ‘x’ number of notes of each one, five, ten and twenty rupee bank notes.

According to question:

x + 5x + 10x + 20x = 1080

⇒ 36x = 1080

⇒ x = 1080 ÷ 36

⇒ x = 30

So, total bank notes that Aman has = 4 × 30

= 120

Hence, ‘120’ is the correct answer.
