susha brought terilon cloth and rope to if rope is 153 mtr long and it is to be cut into pieces of 1 mtr long then how many times will she have to cut it??
Read Solution (Total 5)
-
- There should be 152 cuts
If you take 3 metres cloth
_ _ _ there are two cuts
If you take 6 metres cloth
_ _ _ _ _ _ there are five cuts . .
Like that if you want to cut a n metre cloth into unit pieces the number of cuts required is (n-1).

- Ans.152 cuts
Because when you make the last cut,two pieces are obtained.
this can be explained if we take 2m rope and you have to cut it into 1 mt pieces then only 1 cut is required.
In case of 3m rope,cuts required are 2.
and so on for n meter rope,the no. of cuts required are (n-1).
[There can be one be one one variation for this ques. Suppose you want to cut a 2m cloth into 1/2m long piece.Follow the following steps:
a.find the no. of 1/2m pieces that can cut from 2m rope=2/(1/2)=4{n*2}
b.now the no. of pieces=(4-1)=3{2n-1}
So,the general formula is (2n-1)
