32 rolls
54 rolls
108 rolls
120 rolls
Answer: Option
Explanation:

Number of cuts made to cut a roll into 10 pieces = 9.

Therefore Required number of rolls = (45 x 24)/9 = 120.

When he cut 10 pieces of equal length he will cut 9 pieces last piece will already be of the same length.

That is why 9 cuts for a roll, Just like if you want to divide a box into 10 equal parts you will draw 9 lines and get 10 boxes.

120 is correct answer.

Simply to cut the roll into 10 pieces tailor have to cot 9 times so,
45/9= 5.
5*24=120.

One roll is being cut into 10 pieces.
Rate of cutting is "45 cuts" per minute.

Now to cut a roll into 10 pieces "9 cuts" are to be made.
Which means one roll needs 9 cuts to be made into 10 pieces (hope it's clear).

Now, if 45 cuts are made, think of how many rolls have been cut (that's right) 5 rolls.
You can verify by dividing 45 cuts by 9 cuts (because each roll needs 9 cuts to be made into 10 pieces which give 5 rolls) or multiply 9 cuts by 5 rolls which will give 45 cuts a minute (which is the cutting rate).

Now if 5 rolls are cut in a minute,
In 24 mins- 24*5= 120 rolls will be cut.
Thank you!

4.5*24 =108 it is the right answer.

1 role = 10 pieces [ roll of equal length].

Again,
1 role = 45 cuts [ cut at the rate ] & [ by giving 45 cuts in a role you can get 10 pieces of fabric].

So,
10 pieces = 45 cuts,
1 pieces = 45/10 = 4.5 cuts.

Mentioned: [He cut at the rate of 45 cuts a minute].

So,
1 minute = 4.5 c.
24 minute = (4.5*24) = 108.

In question not clearly define all roll fabric cut or 10 pieces equal length cut from roll fabric
If all roll fabric cut then the answer is 120.
If 10 pieces equal length cut then answer is 108.

He cuts 5 rolls(45/9=5) In a minute, to cut within 24 minutes, 24*5 = 120 rolls.

In each minute, he cuts 4 and a half roll (4.5 roll).

So in 24 minutes he cuts 108 rolls.
