Tailor cuts each roll of equal length into 10 pieces (clearly it was mentioned, so no need to consider 9 cuts and all).
He cuts at the rate of 45 pieces per minute.
so per minute he cuts 45/10 = 4.5 rolls per minute,
So for 24 minutes: 24 * 4.5 = 108 rolls.
He cuts at the rate of 45 pieces per minute.
so per minute he cuts 45/10 = 4.5 rolls per minute,
So for 24 minutes: 24 * 4.5 = 108 rolls.

9 pieces per roll. 45 pieces ÷ 9 = 5.
5 * 24= 120.
5 * 24= 120.

120 is correct.
When you have 1roll, you don't cut on the sides, the terminals. We only cut the mid parts. Try cutting a piece of paper using a scissor, you will have 9 cuts not 10.

Step1 : 1 Role = 10 Pieces.
Step2 : Rate of Cut = 45 Pieces Per Min ==> 90 pieces per 2 min ==>90 Pieces = 9 roles (from step 1).
So, in 2 min he can cut 9 roles according to this ==> in 24 min= (2 * 12 min = 9 * 12 roles) ==> 24 min = 108 Roles.
Step2 : Rate of Cut = 45 Pieces Per Min ==> 90 pieces per 2 min ==>90 Pieces = 9 roles (from step 1).
So, in 2 min he can cut 9 roles according to this ==> in 24 min= (2 * 12 min = 9 * 12 roles) ==> 24 min = 108 Roles.

Logically nothing is applied about the 10 cuts being 9 pieces. The problem does not state that.

To cut 1 roll, we need( 9cuts/(45 cuts/min))= (1/5 min)
in 1/5 min, we can cut 1 roll,
in 1 min, we cn cut 5 rolls,
in 24 min, we can cut 24*5 =120 rolls.
in 1/5 min, we can cut 1 roll,
in 1 min, we cn cut 5 rolls,
in 24 min, we can cut 24*5 =120 rolls.
