a) 47 inches
b) 44 inches
c) 45 inches
d) 46 inches
Answer: b
Explanation:
$$\eqalign{
& {\text{Shrinking of cloth}}, \cr
& = {\frac{{ {36 – 33} }}{{36}}} \times 100 \cr
& = \frac{{100}}{{12}}\% \cr
& {\text{Second time the strip shrinks,}} \cr
& = \frac{{ {48 \times 100} }}{{1200}} \cr
& = 4\,\text{inches} \cr
& {\text{The}}\,{\text{cloth}}\,{\text{remains}} \cr
& = 48 – 4 \cr
& = 44 \cr} $$
