CEVAP:

In this method, first a fixed based or chain-based simple indexes are computed for different periods and then one of the averages such as arithmetic mean, geometric mean or median is used to find the averages of the found index values. This index also does not take into account the quantity of each item, but it is still a vast improvement on the simple aggregate index. The simple average of relative method is simpler and easier to apply than the simple aggregative method. The only disadvantage is that it gives equal weight to all items.
