Paasche quantity

Hi good evening,

Appreciate your help with the below. I am following all the steps and still not matching with the answer (the book uses the formula so cannot match my workings)

A company buys and uses five different materials. Details of the prices and quantities used for 20X1 (base year) and 20X2 (current year) are as follows;

20X1
MATERIAL QUANTITY UNIT PRICE
F 21000 11
G 56000 22
H 62000 18
I 29000 20
J 31000 22

20X2
MATERIAL QUANTITY UNIT PRICE
F 25000 12
G 52000 26
H 79000 18
I 35000 22
J 36000 23

What is the Paasche quantity index for these products?

The material indexes I managed to work out are below, am I correct till this step?

MATERIAL INDEX
F 119.05
G 92.87
H 127.42
I 120.69
J 116.13

The next step is to then multiply the indexes by the sales of 2012 (or the unit price?) and divide by the total sales (or unit prices?).

I am varying from the answer..

No matter in what way I attempt it I cannot find what I am doing wrong 🙁

Thanks,
Sara
