Q.  The length and breadth of a rectangular piece of land are in the ratio of 5:3. The owner spent Rs 3000 for surroundings it from are the sides at Rs 7.50 per meter. The difference between is length and breadth is_________?

a. 50m
b. 100m
c. 150m
d. 200m


ANSWER: See Answer
 
Let length = 5x meters and breadth = 3x meters

Perimeter = 2 x (5x + 3x) m = 16x metres.

Perimeter = Total cost/Rate = (3000/7.50) m = 400 m.

16x = 400 or x = 25

(Length) – (breadth) = (5 x 25 – 3 x 25)m

= (2 x 25) = 50 m
