Using simple average of relatives method, the price index for 2011, taking 2001 as base year, was found to be 127. If $\Sigma p_0 = 263$, then x and y from the following data are :

Commodities	A	B	C	D	E	F
Prices (in Rs.) in 2001	80	70	x	20	18	25
Prices (in Rs.) in 2011	100	87.50	61	22	y	32.50

For the given five values, 17, 25, 21, 35, 43, the three-year moving averages are:

Given $\sum p_0 q_0 = 800$, $\sum p_0 q_1 = 1500$, $\sum p_1 q_1 = 1300$ and $\sum p_1 q_0 = 900$, where subscripts 0 and 1 are used for base year and current year respectively. The Paasche's index number is:

Irregular variation in a time series are not caused by :

The 3-year moving averages for the loan (in lakh ₹) issued by a finance company for startups in different cities of India based on the values given below will be:

If Paasche's index number is 160 and Laspeyre's index number is 250, then Fisher's index number is :

Given that p$_0$ and p$_1$ represent base and current prices of a commodity, q$_0$ and q$_1$ refer to the base and current quantities, then the formula used to calculate price relatives is :
