The breadth of a rectangular hall is 5/8 of its length. If the area of the floor is 160 metre², then what is the difference between the length and breadth of the hall?

A8 metre
B6 metre
C10 metre
D4 metre

Correct answer: B

Let length = L, breadth = 5L/8. Area: L × 5L/8 = 160, so L² = 256 and L = 16. Breadth = 10, difference = 6 metre.
