A) 75 m
B) 50 m
C) 90 m
D) 60 m
Correct Answer: B
Solution :
[b] Let the length and breadth of plot are 5x and 3x respectively Perimeter of plot = 2(5x + 3x) = 16x According to question \[16x\times 7.5=3000\] \[\Rightarrow \] \[x=\frac{3000}{16\times 7.5}=25\] \[\therefore \] Length of plot 5x = 125 m Breadth of plot 3x = 75 m \[\therefore \] Difference = 125 ? 75 = 50 mYou need to login to perform this action.
