Answer : 2. "40%"
Explanation :
Answer: B) 40% Explanation: Lets say shyam sells at 100, ┬а Since Ram sells 25% cheaper than Shyam, ┬а Therefor Ram sells at less than 25% of100 or 75 rs. ┬а Ram sells 25% dearer than Bram or 125% of Ram =100% of Bram or ┬а 125% of x (say x price of bram )=75rs.or 100% of x =60rs.hence price of bram is 60rs. ┬а now Bram's good is cheaper than Shyam's as (100-60)x100/100% or 40%. ┬а Hence Brams Good is 40% cheaper than that of Shyam's good.
