Answer : 2. "40%"
Explanation :

Answer: B) 40% Explanation: Lets say shyam sells at 100,   Since Ram sells 25% cheaper than Shyam,   Therefor Ram sells at less than 25% of100 or 75 rs.   Ram sells 25% dearer than Bram or 125% of Ram =100% of Bram or   125% of x (say x price of bram )=75rs.or 100% of x =60rs.hence price of bram is 60rs.   now Bram's good is cheaper than Shyam's as (100-60)x100/100% or 40%.   Hence Brams Good is 40% cheaper than that of Shyam's good.
