A) \[37\frac{1}{2}%\]
B) \[37%\]
C) \[36\frac{1}{2}%\]
D) \[38\frac{1}{3}%\]
Correct Answer: A
Solution :
Let the length be 100 m and breadth be 100 m, then New length = 160 m. New breadth = x, then\[160\times x=100\times 100\] \[\Rightarrow \] \[x=\frac{100\times 100}{160}\] \[\Rightarrow \] \[x=\frac{125}{2}\] Decrease in breadth\[=\left( 100-\frac{125}{2} \right)%=37\frac{1}{2}%\]You need to login to perform this action.
