With regard to Laspeyre's and Paasche's price index numbers, it is maintained that, "If the prices of all the goods change in the same ratio, the two indices will be equal, for then the weighting system is irrelevant, or if the quantities of all the goods change in the same ratio they will be equal, for then the two weighting systems are the same relatively." (Karmal) Prove the above.
