Taking 1975 as the year, with an index number 100, calculate an index number for 1979, based on weighted average of price relatives derived from the table given below:

The weights are now change if so that the weight for A is 40 and C is 10 and the total weight is 100. If the value of the index no, in 1979 with the changed weight is 182, calculate the weights applied to B and D.
