Find x if the Price Index Number by Simple Aggregate Method is 125.

Commodity P Q R S T

Current Year
Price (in ₹)
12 18 x 28 22
योग

उत्तर

Commodity Base year
price
Current year price
p0 p1
P 8 12
Q 12 18
R 16 x
S 22 28
T 18 22
Total 76 x + 80

From the table, `sum "p"_0 = 76, sum "p"_1 = "x" + 80`

Given, Price Index Number (P01) = 125

Since `"P"_01 = (sum "p"_1)/(sum "p"_0) xx 100`

`125 = ("x + 80")/76 xx 100`

∴ 125 × 76 = (x + 80) × 100

∴ 9500 = 100(x + 80)

∴ 95 = x + 80

∴ x = 95 - 80

∴ x = 15
