Question

The cloth required to make a trouser is 1 m 20 cm. How many trousers can a tailor stitch using 47 m of cloth? How much cloth will be left?

• A. 39, 0.2 m
• B. 38, 0.2 m
• C. 39, 0.3 m
• D. 38, 0.3 m

Answer 1

The correct option is A 39, 0.2 m

Given
The cloth required for one trouser
= 1 m 20 cm
= 120 cm ($\because$ 1 m = 100 cm)

Total length of cloth available
= 47 m = 4700 cm

Numbers of trousers tailor can stitch $=\frac{\text{Total length of cloth}}{\text{The cloth required for one trouser}}$

$=\frac{4700}{120}=\frac{470}{12}$

$\begin{array}{c}3900\\ 12\overline{)470}\\ \underset{–}{0360}\\ 110\\ \underset{–}{0108}\\ 020\end{array}$

So tailor can stitch 39 trousers with 47 m of the cloth and 0.2 m of the cloth will be left.
