B. 44 inches

C. 45 inches

D. 46 inches

Answer: Option B

Solution(By Examveda Team)

$$\eqalign{ & {\text{Shrinking of cloth}}, \cr & = {\frac{{ {36 - 33} }}{{36}}} \times 100 \cr & = \frac{{100}}{{12}}\% \cr & {\text{Second time the strip shrinks,}} \cr & = \frac{{ {48 \times 100} }}{{1200}} \cr & = 4\,\text{inches} \cr & {\text{hence,}}\,{\text{the}}\,{\text{cloth}}\,{\text{remains}} \cr & = 48 - 4 \cr & = 44 \cr} $$

    36 inches is required to shrink 3 inches
    then 48 inches is required to shrink (3*48)/36 = 4 inches
    so after shrinking, it will be 48 - 4 = 44 inches
