From I. 1 : b = 3:2 From II. length = 48 metres Cost of flooring per square metre = ₹ 850 . Using I and II. b =
48×2
3
= 32 m Thus area = (48 × 32) m2 and total cost of flooring = 3 (48 × 32 × 850) m2 Thus I and II are sufficient to get the result. From III 2(1 + b) = 160 m Cost of flooring per square metre = ₹ 850 Therefore using any two of the given three statements, we can find the answer.
