Marks: +1, -0

By selling

33 \mathrm{~m}

of cloth, a draper loses an amount equal to the selling price of

3 \mathrm{~m}

of cloth. Find his gain or less percent.

gain $8{1}/{3} \%$
loss $8{1}/{3} \%$
gain $7%$
loss $7%$

Solution:

(b) Suppose that price of

1 {\m}

cloth is

₹ 1

Then, Selling price of

33 {\m}

cloth

=₹ 33

and loss

=₹ 3

(S.P. of

3 {\m}

)
∴Cost price

=₹(33+3)=₹ 36

∴

loss

\%={{\loss} ×100}/{{ \cost \price }}={3 ×100}/{36}

={100}/{12}={25}/{3}=8 {1}/{3} \%

So, loss

8{1}/{3} \%

.
